TnE Position of tiie Winter Quarters. 
Tho latitude depends on seven sets of circum-meridian-altitudes, taken in Septem¬ 
ber, 1853, and May, 1851, each set consisting of eight to twelve single observations; 
the first set with theodolite, tho rest with sextant and artificial horizon.

Tho longitudo is derived principally from moon-culminations and moon-culmina¬ 
ting stars, by three occultations of Saturn, December 13, 1853, January 8 and 
February 5, 1854, and an occultation of Mars, February 13, 1854, and a solar eclipse, 
May 15, 1S55.

The latitudo of Littleton Island is determined by a set of circum-meridian-altitudes 
of the sun, made on the east end of tho island; the single observations give, (cor¬
