CAPTAIN REED. The arrival of several of the officers of the Vixen ena- He was the youngest son of the late President Reed, In private life his characteristics were probity, cheerfulness, extensive intellectual acquirements, a most unaffected diffidence of his own sterling merit-together with a general sobriety and chasteness of conduct, a due sense of moral and religious obligations, not always the recommendations and sometimes not even the aim of young gentlemen of the sword. He acted as 2d lieutenant of the Nautilus in the memorable attack on Tripoli, in August 1806, after the death of Capt. Somers; and 1st lieutenant James Decatur took command of that vessel, stood into the harbour with the utmost gallantry and skilfulness, and effectually covered the gun-boats in their operations. For his conduct on that occasion he was noticed by Com. Preble in his general orders, issued on the termination of that bold and successful enterprize. Lieut. Reed afterwards accompanied Gen. Eaton's detachment to the coast of Africa, and served on board the vessel which co-operated with him on that romantic expedition. When war was declared against England last summer Capt. Reed solicited employment, though his health was extremely delicate. He was ordered to a command to the southward,whither he repaired immediately notwithstanding the unhealthiness of the climate at that season. The death of Capt. Gadsden preferred him to the comThe sea air, in a great degree mand of the brig Vixen. restored his health: but it was his peculiar hard fate to be captured by a force so superior as to preclude any contest, (the Southampton frigate) then to be shipwrecked on an inhospitable coast, and finally to die a prisoner among strangers. During all these reverses, however, he preserved that equanimity and resolution which never forsook him. When the Southampton and Vixen ran ashore, in the night, the English crew became mutinous from intoxication, and what was saved from the wrecks was principally due to the exertions of the American seamen, under the direction and encou ragement of Capt. Reed. For this generous interposition he received the public acknowledgments of Sir James Yeo, the British commander, and an offer of his parole to return home, but would not leave his officers and men behind him, and chose rather to remain with them in the unwholesome atmosphere of which he was, unfortunately, the first victim. He died, after four days illness, of a fever brought on by the fatigues, anxiety, and exposures incident to his painful and mortifying situation. His enemies paid those honours to his remains which the brave of all nations render to each other. His interment was attended by the British officers, and a detachment from the garrison, who committed him to the earth with the ceremonies of a military funeral. The naval annals of his own country now blazing with recent renown, will not withhold a suitable testimonial to the memory of an officer, whose lot it was at such a time to undergo the total frustration of his ambition, and shipwreck, and captivity, and an untimely death.-Nat.

She was directed to bring out a tomb-stone to be placed over the grave of Capt. Reed, who is buried in the church yard of Spanish town. "Through the indulgence of the gentlemen to whom the stone is addressed, we have had an opportunity of viewing a beautiful slab of marble, with the following feeling record of the remembrance in which the friends of the deceased cherish the kindness shown to him in captivity."

The head of the Schuylkill Canal, since the extension of the work, is Mill Creek. At the junction of that stream with the Schuylkill, a village is already laid out; and although at present rather wild and rugged in its appearance, we have no doubt it will in a short time become a flourishing place. The site is directly on the canal, where commodious wharves and landings are now being built. The village has received the name of Port Carbon. In the very precincts of the place, several mines of superior coal have been opened, and as there is a gradual descent from the mines to the town, the facilities for transportation are very superior. In viewing the site of the village and its vicinity, we were attracted by a very cheap and simply constructed rail road, laid by Mr. Abraham Pott, from the landings into a fine vein of coal which he has just opened. The rails are entirely of wood, and it is not intended to plate them with iron. This, it is true, will increase the friction, and consequently the resistance to the cars, but the road is so graduated, that one horse may with ease draw ten tons, or from 50 to 75 tons a day. The coal in the neighbourhood of Port Carbon is as plentiful and of as good quality as in any part of Schuylkill county. [Miner's Journal. Meadville, (Pa.) July 31. On Thursday afternoon, the 24th inst. a severe thunder gust passed over our village. A portion of the electric fluid struck two trees in front of Mr. Gibson's hotel, when he and another gentleman were within a few feet of its effects; yet neither they nor any others were injured, though several in the vicinity perceived a sensible shock. low this place, and a quarter of a mile from his house. His three sons, three sons of Mr. Samuel Sloan, and three other young men, two of whom were strangers from the lower part of Ohio, were at work in a wheat field previous to the tempest. Very imprudently, they repaired to a large elm tree for shelter from the rain which came down in torrents. A sickle had been stuck into the bark of the tree as high as one could reach.Some of the young men stood leaning against the tree, one directly under the sickle, James Van Horne just before this one, others were seated on the roots of the tree jutting above the ground, and one was under a shock of wheat perhaps a rod off. The lightning struck the top of the tree, and 15 or 20 feet from the root, the body, gouging out a furrow, At a moment little expected, all these nine young men were instantly senseless! It is painful to add that Joseph Sloan was killed; yet, wonderful to relate, the rest escaped with their lives! He was seated on a large projecting root of the tree.The lightning struck his head, temples, back of his neck, and passing under his chin, went off following his body in various directions. He was at the age of nearly sixteen years, the eldest son of his parents, an active and promising youth, on whom his enfeebled father depended much for aid in supporting his large family. It is supposed that all the survivors must have remained in a senseless state, about half an hour-none in the neighbourhood suspecting the calamity till one of the young men who was so far recovered as to give the alarm. He hastened home, and like one of the messengers of Job, as soon as he entered the house, exclaimed-mother they are all dead but I. The feeling of a tender mother, unforewarned, on receiving such tidings, may be conceiv ed, but cannot be expressed. A messenger was despatched for a physician, and others with a wagon to the fatal spot, and all were brought in the wagon except one, who by this time with some assistance, was able to walk. James Van Horne remained senseless for some hours, and for a time it was feared that the vital spark had fled. Dr. Bemus arriving soon, threw upon him a bucket of cold water, which had a favourable resuscitating effect; put his blood into circulation, so that he was very much relieved by the lancet; yet the exercise of his reason was not recovered till late in the evening. He is still considered as in a critical situation. The rest who were providentially spared with life, are in a hopeful way, yet most of them complain of much soreness. Their hair was singed; a boot of one was ripped and tore at the sole; the waistcoat of another had s large perforation; and most of them have livid streaks in various parts of their bodies. It is worthy of remark, that upon the breast and other parts of the body of Joseph Sloan, were distinct and well-defined impressions of elm twigs and leaves with the minutest ramification of their numerous fibres-a number of such twigs and leaves having been torn from a limb a little above him, and lying on the ground about him-the effect of the lightning.—Norristown Register.

PITTSBURG MINERAL SPRING. A Chemical Analysis of the Pittsburgh Mineral Spring. From Professor Silliman's Journal, April 1828. W. MEADE. The Pittsburg Mineral Spring, is pleasantly situated on the farm of John S. Scully. Esq. in St. Clair township, Allegheny county, four miles south-west of the city of Pittsburg, and two miles south of the Ohio river. It issues from the fissures of a rock, on the side of a small hill, and discharges about a gallon of water per minute, which is conveyed through a tunnel into a reservoir, from which it is pumped to supply the bath house. The water in the spring, when undisturbed for a few hours, is covered with a thin white pellicle, which after some time assumes an iridescent appearance. It then falls to the bottom, and is renewed, if the water be not disturb ed, as may be more particularly observed every morning. When the water is first taken from the spring, its appearance in a glass is perfectly clear; its taste is lively and rather pungent, with a peculiar ferruginous flavour, and an odour which has some resemblance to the scour ing of a gun barrel, and which is easily recognised as arising from an impregnation of sulphuretted hydrogen gas. If the water is allowed to remain for some hours in a glass, it loses, in some degree, its transparency, as well as its lively and pungent taste; numerous air bubbles are extracted from it, and a light deposit takes place on the inside of the glass, which renders it pellucid. Vessels which are constantly used become lined with an ochry incrustation, which is with difficulty removed, and the bottom and sides of the well, as well as those substances over which the water flows, contain a sediment of the same nature. The temperature of the spring is nearly the same at all seasons of the year. In the month of August, when the atmosphere was as high as 85 of Fahrenheit, the temperature of the water was only 54. The specific gravity of the water differs little from the purest water. When compared with distilled water it is as 1002 to 1000. Having made these preliminary remarks on the exter nal qualities of the spring, I proceed to an experimen tal inquiry into its chemical properties. OL. II. 13 NO. 34. 1. Examination of the contents of the water by tests and reagents. EXPER. 1. Litmus paper when dipped into the water fresh from the spring has its colour immediately changed from blue to red, but the colour is fugacious: nor will the water when boiled produce any such effect, a decisive proof that this change was produced by the presence of uncombined carbonic acid gas, and not by a fixed acid. 2. Paper stained with tumeric is not changed in colour by this water, nor could it well be expected as the carbonic acid gas would repress the effect of this test. 3. Lime water produces an immediate turbidness and precipitation when added to this water, yet a variety of circumstances are to be attended to in the application of this test. The usual directions which are given are, that the lime water shall be added to it in equal quantity. This, however, if the mineral water is saturated with carbonic acid, as in the case of the Ballston water, is too much, and if the water contains but little carbonic acid, it is not sufficient to decompose the same water, in order therefore to ensure a complete and permanent precipitation of the lime, it requires four cubic inches of the water of this spring to decompose three cubic inches of lime. It is evident, therefore, that the greater quan tity of carbonic acid gas, which is contained in a mine. ral water, the less of that water is required to produce the requisite change, so that by observing this rule, an experienced chemist can form a tolerable accurate judgment of the quantity of carbonic acid contained in any mineral water. 4. Tincture of galls, when poured into a glass of this water strikes an immediate purple colour, which after standing for some time, increases in intensity, but no such change takes place if the water has been previous ly boiled. 5. Prussiat of potash.—This test produces an immediate change in the colour of the water; it first becomes green, and after standing some hours assumes a blue colour. 6. Nitrat of silver.—When a few drops of this test are added to a glass of this water, a dense white flocculent precipitate is thrown down, which after some time changes to a light purple colour. 7. Acetate of lead, throws down an immediate dense white precipitate, the colour of which is rendered a shade darker when allowed to stand in the glass for a few hours. This precipitate is partly dissolved when a few drops of nitric acid are poured on it, which shows that a small quantity of sulphuric, as well as muriatic acid, is present; muriat of lead being soluble, while the sulphate is perfectly insoluble in any acid. 8. Muriat of Barytes, produces a white cloud when permitted to stand for some time, a precipitate falls which is not soluble in nitric acid. 9. Oxalat of Ammonia, produces a slight turbidness but scarcely any precipitate. 10. Liquid or pure ammonia, has no effect on the water either when fresh from the spring or when concentrated by boiling. 11. Carbonat of potash, does not disturb the transparency of the water. 12. Sulphuric acid.—This acid produces no change. II. Inferences to be drawn from the above experiments. If it was only required to determine the quality of this water, and the nature of the ingredients, these experiments would be nearly sufficient; but no chemical investigation will be deemed satisfactory at present which does not exhibit the exact proportions of the different ingredients. Before however we proceed further in the investigation, the use of tests and reagents become an important guide; by their means future experiments may be conducted with more precision, and when we proceed to evaporation, much time and labour are spared in looking for those substances which we had previously ascertained by reagents not to be present. Thus having discovered iron by experiments 4 and 5, and that it was held in solution by carbonic acid, it was in vain to look for any metallic salt, and we have only to determine the quantity of iron which is thus suspended. Experiments 1 and 3 have shown the presence of a considerable quantity of carbonic acid gas. Experiments 1 and 4 show that the iron is held in solution by this gas. Experiments 6 and 7 demonstrate the presence of muriatic acid combined with a base. Experiments 8 and 9 show the presence of a small quantity of sulphuric acid and of lime. It now remains to confirm these, by evaporation and more direct experiments, as well as to determine the quantity of each substance in a given quantity of water. III. Examination of the gaseous contents. As many of the most important qualities of mineral waters arise from the gas with which they are impregnated, there is no part of their analysis which requires more attention. In order to determine the quantity of this gas I proceeded in the manner which I have pointed out in my essay on the mineral waters of Ballston and Saratoga, and which I have uniformly found successful. A plate of the instrument which I used on those occasions, will be found in the publication alluded to. It consists of a tin vessel calculated to hold one quart of water. A covering was soldered on it, and no opening left except one at the top, to which was adapted a small tube about half an inch long, and one third of an inch in diameter. A graduated decanter was connected with this, which was filled with hot water. Heat was then applied to the tin vessel, when the gas which was extricated from one quart of water was collected in the glass vessel graduated into cubic inches. I found that the whole of the gas which was extricated from one quart of the water amounted to eighteen cubic inches, which, when passed through lime water, was entirely taken up by it, so that it consisted entirely of carbonic acid gas. Some surprise may be excited at finding so small a quantity of carbonic acid in this water, when we compare it with the waters of Saratoga and Ballston, but let it be recollected that they have no resemblance; and if we refer to the analysis of the most celebrated chalybeates in Europe, and even in this country, none of them are stated to contain more, and few of them so much. It is even probable that if this water were examined when immediately taken from the spring, it would be found to contain more of this gas. IV. Examination of the contents of the Pittsburg Mineral Spring by evaporation. This powder when exposed to the atmosphere for several days, showed no signs of deliquescence, nor was it sensibly increased in weight. In order to determine the component parts of these four grains, I proceeded in the following manner. I poured over it, in a small phial bottle, about half an ounce of alcohol of the specific gravity .827, and shook it repeatedly for twenty-four hours, then filtered it carefully, when I found it had lost in weight only half a grain, which was the whole that the alcohol had taken up. The residue, now reduced to three and a half grains, was treated with an ounce of pure distilled water, and having left it sufficiently long to complete the solution of whatever was soluble in pure water, I again filtered it carefully, and dried the rcsiduum, which was now reduced to one and a half grains. Only this residuum, which resisted the action of alcohol and of distilled water remained to be examined, and, as from former experiments I had satisfied myself that it must consist principally of the iron and earths contained in the water, I re-dissolved it in dilute marine acid, which took up the whole of it, except half a grain of white powder, which remained on the filter, and which not being soluble in dilute marine acid, was found to be gypsum, or sulphate of lime. We have now three solutions, which we shall examine in the following order:- First-That which was taken up by the alcohol, and consisted of only half a grain. This could be only mu riate of lime or muriate of magnesia. Having converted it into an aqueous solution by previous evaporation, and subsequent dilution in a small quantity of distilled water, I found that it was precipitated by pure ammonia, and showed the presence of marine acid by the addition of nitrate of silver. Thus we have decided the presence of muriate of magnesia, half a grain. Second-It will be perceived that the distilled water had taken up two grains of the residuum, from the solution in alcohol. To ascertain the properties of this, I evaporated this aqueous solution over a lamp in a glass vessel. When the evaporation was nearly finished saline cubic crystals appeared, which on examination, were found to be wholly muriate of soda, or common salt. The third and last solution in marine acid, which consisted of one grain, was diluted with distilled water, and as I had no reason to doubt it contained the whole of the iron with which the water was impregnated, I added a few drops of succinat of ammonia, which immediately threw down a brown precipitate. When the whole of it was precipitated, the solution was filtered, and after the residuum had been exposed to a red heat it was weighed and examined, when it was found to consist of one grain of oxide of iron. The analysis of the Pittsburg Mineral Spring having been thus completed, I shall here recapitulate the whole of its contents as it appeared from experiments, as follows-20 Muriate of soda Muriate of magnesia Oxide of iron Sulphate of lime 10 40 Total, Quantity of carbonic acid gas in one quart of water. V. General remarks on the sensible properties of the Pittsburg Mineral Spring, and of its comparative qualities as resembling those most celebrated in Europe and Ame rica. The experiments which have already been detailed throw great light on the qualities of this water, and ena-eighteen cubic inches. ble the experienced chemist to decide upon the nature, but not on the quantity of the different substances with which it is impregnated. To make an accurate estimate of these I proceeded to evaporate one quart of water in a glazed China vessel, placed in a sand bath over a furnace. Heat was gradually applied, but never allowed to exceed 180 or 200 of Fahrenheit, when the gas began to arise, the water became slightly turbid, and a light pellicle appeared on its surface, which gradually subsided to the bottom of the vessel, and when the water was evaporated to dryness, the whole of the residuum or solid contents which was collected, amounted to 4 grains. When we take a view of the component parts of this mineral water, as they appear by analysis, we must perceive it is an uncommonly pure water, possessing all the qualities of a strong chalybeate. Those who are not accustomed to examine waters of this description, may at first feel some surprise at not finding it to contain a greater quantity of solid contents, but when we refer to the analysis of similar springs both in Europe and Ame rica, as performed by the most distinguished chemists in each country, we shall find that the Pittsburg spring possesses qualities equal to any of them, and to many is greatly superior. As an instance in point, I shall take for example, in the first place, the waters of Tunbridge, in England, one of the most celebrated and established chalybeates of that country, on which many treatises have been written, and much discussion taken place with respect to its medical qualities. According to the analysis of the celebrated Dr. Babington, the Tunbridge water contains only one grain of oxide of iron in a gallon of water, while the Pittsburg spring contains four times as much, viz. one grain in a quart. It also contains only ten cubic inches of carbonic acid gas in one gallon of water, while the Pittsburg spring contains eighteen inches in a quart. On the whole, its solid contents do not amount to more than one-fourth of the quantity we find in the Pittsburg spring; and yet this ineral spring is as much frequented as any in England, and is known to possess most valuable medicinal properties in those diseases to which it is applicable. But we shall refer to various mineral springs in this country of established reputation, where extensive buildings have been erected, and which are frequented with great advantage, by invalids from all parts of the union. In doing so I shall select those whose qualities are precisely similar, and whose virtues are to be attributed chiefly to their chalybeate qualities. of them do, a considerable quantity of a neutral salt, the The effects of iron on the system are sufficiently numerous in the animal economy; it stimulates the fibres of the stomach and abdominal viscera; it augments the tone of all the muscular fibres; strengthens the nerves, and gives the whole weakened system remarkable energy; it increases the strength of the pulse, and from its use, the pale emaciated countenance assumes a healthy florid colour. With regard to the various preparations of iron, those which seem best calculated for the purpose, are such as are most certainly conveyed into the blood, and most casily converted into oxide. Of these, iron dissolved by carbonic acid, and held in solution in a mineral water, seems by far preferable, and with respect to quantity, experience has shown us that small doses of iron produce better effects than large ones, particularly when persevered in, as should always be the case, for a larly made by the celebrated Dr. Cullen, and should always be attended to. Mineral waters, he remarks, often produce cures which we in vain attempt to perform by the combinations of iron in our shops, even although those waters contain nothing but iron; this is manifestly owing to the weakness of the dose, in proof of which we find that the strongly impregnated waters seldom answer so well as those which we commonly re The mineral water of Schooley's mountain, in the state of New Jersey, is perhaps one of those which has for many years sustained the greatest reputation as a chaly-considerable length of time. This observation is particubeate. Having visited it myself, I have had an opportunity of observing its powerful medicinal qualities as a chalybeate, but for an accurate and able analysis of it, I must refer to an essay of Professor M'Neven, of New York, where it will be found that the whole contents of one gallon of the water are only about eight grains, two grains of which consist of oxide of iron-and that one quart contains nineteen inches of carbonic acid gas. Here then we have a mineral water of acknowledged re-ject. putation which does not contain much more than onefourth the quantity either of iron or saline solid contents, which we find in the Pittsburg spring, and as nearly as possible the same quantity of carbonic acid gas. I could refer to many other springs of the same nature, in this country, possessing the same properties, but scarcely one have I ever examined, possessing them in the same degree; among others, the Yellow Springs, in Pennsylvania, where beautiful buildings are erected, and accommodations of every kind are prepared for the invalid; yet, having myself made an analysis of this water with great care, I found that it had no claim to rank as a chalybeate of a superior order. In fact, all those mineral springs which are impregnated with iron, held in solution by the carbonic acid gas, in whatever country they are situated, are properly called chalybeates, and are endowed with nearly the same medicinal properties. What these are I shall now proceed to point out. VI. On the medicinal qualities of the waters of the Pittsburg Mineral Spring, with observations on the effect of such waters on the system. The operation of the chalybeate waters, perhaps the most important class of natural medicines, has greatly occupied the attention of practical physicians. Much refinement has been introduced into the subject, which it is my intention to avoid, as my main object is to point out the principal effects which such waters produce on the system, and the diseases to which they are more particularly applicable. Let me however premise, that though the principal virtues in those waters are derived from their chalybeate impregnation, yet certain differences will arise, which modify or alter their operation. These may be traced either to the presence of an active neutral salt or to a large excess of carbonic acid. I cannot exemplify this better, than by referring to the waters of Ballston and Saratoga, all of which contain iron in greater or less quantity, but containing also, as most The Chalybeate water at Pittsburg I can venture to recommend for all purposes for which Chalybeates in general are given, and though the quantity of iron is small, yet it is equal to that contained in some of the most celebrated German waters, and greater than in many of those which are most esteemed and frequented in this country. The mineral spirit, or fixed air by which the metal is held in solution, should by no means pass unnoticed, as it is an agent possessing no small powers over the human frame, and if properly applied becomes one of the most useful remedies. To this principle most mineral waters owe their activity; it is this agent which holds many of their most powerful ingredients in solution, and enables them to pervade the remotest recesses of the human frame. With these observations on the effect of chalybeates on the system, we are prepared to enter into the medicinal qualities of the Pittsburg spring. The first effect of those waters, and which is easily and distinctly remarked in the water at Pittsburg, is de. cidedly of a stimulant kind. Soon after taking a few glasses of it, the pulse is increased in strength, the patient if previously chilly and pale, feels a glow occasioned by the increased circulation, and by persevering in the use of the water for a few days, the appetite becomes greatly increased, and the general spirits and health improved; these effects are more striking in some than others. It is not uncommon, however, on beginning a course of this water, for the patient to experience nausea, vomiting, and pain about the region of the stomach, or else a heaviness of the head, slight vertigo, and sense of fulness over the whole body. Sometimes these are so troublesome as to show that it was not adapted to the nature of the complaint, and to forbid the use of it, but in general these symptoms soon disappear after a little use, and particularly when an increase |
