Those fall into the bottle and are retained, while the fluid is forced back into the bladder by subsequent pressure on the bulb, again to serve its purpose of raising more fragments, which are in turn deposited in the bottle. The process is continued till the debris is entirely removed.-[Ex.

HYGIENE OF RICE CULTURE.-A German physician, Dr. Ullersperger, has recently received a prize from the medical society of Valencia, in Spain, for an essay on the best means to preserve the health of the rice cultivators. It is generally known, that as a class, they rarely attain the age of forty years, falling victims to the marsh fever. Dr. U. recommends that rice culture be avoided where good drainage can not be obtained, that instead of common rice the varieties known as Oriza sativa imperialis, Oriza montana and Panicum crus galli, be planted, which requires much less moisture to perfect them, that the houses of the workmen be well situated, aired and drained, that their food be nourishing and include wine or brandy in moderate quantities, and that they be encouraged to smoke tobacco, which the author regards as an efficient anti-masmatic.

EFFECTS OF VINEGAR UPON THE SKIN.-By the use of vinegar, the Spanish General Vitellis made his skin hang about him like a pelisse. Another Spaniard exhibited himself to Van Horn, Silverium, Piso, and other learned men at Amsterdam; he could draw the skin of his shoulders up to his mouth; and draw the skin of his chin to his breast like a beard; or up to his head so as to cover his eyes. It is supposed to act on the yellow contractile tissue, and has been suggested for use against the contractions caused by burns.-Med. Gaz.

A USEFUL HINT.-In Vienna the use of sulphate of iron as a deodizer has had a most beneficial result. According to La Presse the rats have been so effectually destroyed by the use of green vitrol, that recently Prof. Hurd was unable to procure a supply of these animals for experimental purposes. There is no better or cheaper substitute known as a deodorizer, and if it results in a whole

sale destruction of these pests we would advise its use freely.-[Ex.

TO REMOVE STAINS FROM LINEN.-To remove wine, fruit, or iron stains, wet the spot with a solution of hyposulphite of soda, and scatter some pulverized tartaric acid upon it; then wash out as usual. Strong vinegar can be substituted for the tartaric acid if necessary. As the hyposulphite of soda is largely employed by photographers, its price has been greatly reduced, and it can easily be obtained for use in the laundry.-[Ex.

EXTRAORDINARY OPERATION.-Dr. Bohm, a celebrated German surgeon, has recently performed the operation of separating two female children, five years of age, who were joined together in the same manner as the Siamese twins. The German papers state that the operation was attended with perfect success; but one of the patients seems to have died the same day. The survivor is in good health. New York Med. Record.

Prof. Ludwig Boehm, whose fatal illness we reported a short time since, deceased on the first day of August. Among other things Prof. Boehm was distinguished for the best description extant of the intestinal glands; and his teachings upon the anatomical changes in cholera are classic to this day. He also published important works on strabismus, on the accommodation of the eye, and on other ophthalmological subjects.-Med. & Surg. Jour.

DEODORIZED CARBOLIC ACID.-Carbolic acid may be deodorized by mixing it in a crystalized form with twice its weight of gum camphor, and adding whiting to the compound. In this form it is said to be valuable both as a disinfectant and as a protection to furs against moths.-[Ex.

There are only twenty-four homopathic journals in the entire civilized world. Half of these are in America. So says Dr. T. C. Duncan, of Chicago.—The testimony

-In England some journals urge the propriety of medical men securing patents for instruments and surgical appliances. The New York Medical Gazette advocates a similar view. The adoption of this course will not be sanctioned by American physicians.

Gaz.-From a long series of experiments it has been demonstrated that osseous growths can be produced at will by transplanting the medullary matter of bones, thus proving medullary matter to be as efficient in the genesis of bone as is the periosteum. The editor of this journal has long been advocating the fallacy of the old axiom that "denuded bone will die," and has collected facts as well as principles to show that the periosteum is not necessary to osteogenesis. The genesis of bone from transplanted medullary substances is a new and strong link in the chain of the argument. Mr. Potter treats nævus by the injection of carbolic acid.
