XIII. THE GREAT COMET OF 1843.

BY EENJAMIN PEIRCE, A. M.

Perkins Professor of Astronomy in Harvard University.

On the 27th of February, this comet was seen nearly at midday in Conception, S. A. Captain Peleg Ray, "a man of sound judgment, a very accurate observer, and correct man," observed it in that city, and on that day, at 11 A. M., at the East of the Sun, its bearing from the Sun being almost precisely East, with very little perceptible Southing. Its distance from the Sun was only 5 minutes, or of the Sun's apparent diameter. "He did not," says William Mitchell, of Nantucket, in a letter describing this observation, "measure the angle, his instruments being on board of the ship, some distance below the city; but he took great pains to estimate the apparent distance, and, being so near the Sun, thinks he has done it very nearly. I have tested the day and hour in a most satisfactory manner."

On the 28th of February, the comet was seen by day in various parts of New England, the East and West Indies, and the South of Europe. The only exact observation upon its place was made by Mr. F. G. Clarke, of Portland, Maine; and this is much the most valuable single observation which was made upon the comet, and more so, probably, than any observation which has ever been made upon any comet. The time of observation was 3h. 2m. 15s. Portland mean solar time, and the observed distance, which Mr. Clarke thinks may be depended upon to 10", was 4° 6' 15" from the farthest limb of the Sun to the nearest limb of the comet; the bearing, as nearly as it could be ascertained by the compass, was E. by S. S. of the comet from the Sun. Mr. Clarke says, "the opacity of this comet was remarkable; I fully believe that it might have been seen on the Sun's disk. It resembled a white cloud of great density." He thought, that the tail was fully equal to the nucleus in brilliancy, and adds, "I observed no difference throughout." He also described the head as being definitely distinct from the tail; and the extremity of the tail, most remote from the Sun, was perfectly well defined, and distinctly rounded off. This last observation is insisted upon quite positively by Mr. Clarke, although it seems to be at variance with that of other observers, whose accounts agree much more closely with that of Amici of Florence. Amici saw the comet at noon, and stated "the mass, examined by an opera glass, to be like a flame, badly defined, three times as long as it was wide, very luminous towards the Sun, and a little smoky at the East." An observer at Woodstock, Vt., says that "on viewing the comet through a common three-feet telescope of moderate

power, it presented a distinct and most beautiful appearance, exhibiting a very white and bright nucleus, and a tail dividing near the nucleus into two separate branches, with the outer sides of each branch convex, and of nearly equal length, apparently 8° or 10°, and a space between their extremities of 5 or 6°." This account appears irreconcilable with the same observer's estimate of the length of the comet's tail, which was only 3°, and which is the same with that of the observers at New Bedford and Waterbury.

During the first week of March, the splendor of the comet in the Southern hemisphere is described as altogether surpassing any thing which it afterwards exhibited to Northern observers. On the 1st of March, it was seen at Pernambuco, and on the 4th, it is described by H. A. Cooper, Esq., the British Consul in that city, "as particularly small, without any nebulosity, but of extreme brightness, of a golden hue, and a line of the same bright color may be distinctly traced, running directly from it into the tail, for 4° or 5'; the tail is perhaps 30° in length, and is of a brilliant silver color, perfectly opaque, but becoming less and less dense until it is lost in space."

Commander Close, of the ship Ellenborough, estimated the nucleus "to be of equal brightness with a star of the second or third magnitude, and said that the tail had a darkish line from its nucleus through the centre to the end; it was occasionally brilliant enough to throw a strong light on the sea. The tail was observed to have considerable curvature." This dark line was also noticed on the 4th by Capt. Hopkins, on a voyage to India from the Cape of Good Hope, and by Mr. David Sears, Jr., and Mr. Appleton, of Boston, who were in latitude 10% South, and exerted themselves to obtain observations of the comet. At the Cape of Good Hope, the nucleus was seen on the 3d of March, and is described by Piazzi Smyth, Esq., of the Royal Observatory, as consisting of a "planetary disk, from which rays emerged in the direction of the tail. To the naked eye there appeared a double tail, about 25' in length, the two streamers making with each other an angle of about 15', and proceeding from the head in perfectly straight lines. From the end of the forked tail, and on the North side of it, a streamer diverged at an angle of 6 or 7° towards the North, and reached a distance of upwards of 65 from the comet's head; a similar, though much fainter, streamer was thought to turn off South of the line of direction of the tail. On the 5th, the appearance of the comet was considerably changed; the angle of the North streamer with the direction of the tail had been diminishing, and was now South; it had also diminished in brightness. The total length was about 35°. All the rays proceeding from the head were now of uniform brightness, excepting one bright streak, which
