Encke's Comet.

A correspondent of the U. S. Gazette a short time since furnished some calculations of the motions of Encke's comet according to which it has been approaching the earth at the rate of two millions of miles a day, and reducing its distance from us one half in less time than a month. Professor Olmsted of Yale College, in a late communication to the New Haven Palladium, takes the following notice of its appearance—

This interesting body, which visited our sphere in 1829, has again become visible. I had a fine view of it in Mark's telescope last evening (the 28th) from half past 7 to a quarter past 8 o'clock. Its figure is nearly round, and its brightness exceeds that of Sirius the light being more intense towards the central part, and the margin better defined—Indeed, immersed as it is in the evening twilight, it is far more eligible to us than I anticipated. The evenings of the 27th and 28th were unfavorable for observation: but last evening, an hour before sunset, the comet was readily found, being indeed so near the place assigned to it on the ephemeris, that it was only necessary to point the telescope to that part of the heavens about the triangle of Aries and it at once presented itself. Its place is a little south of the star 5 Tauri, and it was about a degree and a half south of 70 Geminorum, according to the Astronomical Society's Catalogue.
