he year 1865. Mr. Clausen of the Dorpat Observatory, Mr,Capocci of Naples, and the astronomers of theHigh-School Observatory, in Philadelphia, each,without the knowledge of the others, have ex-pressed themselves in favour of this short period.Capocci has even thought it possible that it mayreturn three times in that term. Mr. Nicolai, of the Manheim Observatory, hasexamined the effect of a shortening of its periodupon its elements for 1843, and concludes that itis perfectly consistent w7ith all that is known ofits path in the heavens on that occasion. THE THIRD COMET OF 1843. This comet was discovered on the 25th of No-vember, 1843, by M. H. Faye, of the Paris Ob-servatory. It was re-discovered in this countryon the 27th of December, by Mr. J. S. Hubbard,at the New-Haven Observatory. The parabolicelements of several astronomers being found un-satisfactory, M. Goldschmidt, of Gottingen, at therequest of Gauss, computed, in December last, anorbit on the method of the latter, and found a

Great Comet of 1843. COMETS. 299 period of 6§ years. M. Faye, in January, com-puted an orbit on the same method, and found aperiod of 7) years. The astronomers of the Phi-ladelphia High-School Observatory have computedan orbit on a similar plan, from a series of obser-vations, including an interval of 61 days, andfound a period of 6£ years. The motion is direct,the inclination to the ecliptic is 11° 6. The ec-centricity is 0.52. The least distance is 162, andthe greatest is 522 millions of miles from the sun.This comet can never approach within 60 millions of milesof the earth; but its aphelion distance being a little greaterthan that of Jupiter, and occurring near the ascending node,when this event takes place while Jupiter is about enteringthe sign of the Scorpion, they may approach very near eachother and remain so for the greater part of a year. Thisevent occurred in the year 1840, at which time Jupitersattraction for this comet was about a tenth part of the suns,and must have
