The Story of the Comets.

Chap.

1903, though it would have been interesting to have ascertained whether the influence of Jupiter had accelerated its return by 4 months, as Stromgren calculated would have been the case. The orbit of Faye's Comet is the least eccentric of all the short-period orbits. A sketch of Faye's Comet by Tempel will be found on Plate X.

(13.) Tuttle's Comet.

This comet was first seen by Méchain on Jan 9, 1790. It was only followed for a fortnight. On Jan. 11 Messier could see only a confused nebulosity without any indications of a nucleus. It was not reobserved until its return in 1858, on Jan. 4 of which year it was discovered by H. P. Tuttle at Harvard College Observatory, Cambridge, U.S., passing its perihelion on Feb. 23. It was found to be a periodical comet with a period of about 131/2 years. It returned again to perihelion and was seen in Nov. 1871, August 1885, and May 1899. Its orbit has been thoroughly investigated by Rahts.
