Engineer Department primarily for use in the geographical sur- 
veys west of the 100th meridian. The area in the heavens covere 
is nearly one-fourth of the celestial sphere, ene that part that i is 
of use in field work. The aim has been to determine with the 
utmost accuracy attainable the pay Alera ar and the annual pre- 
cessions and proper motions in declination, of these stars, and in- 
cidentally = corresponding elements in R. A. The logs. of a’ 8’ 
e' and d@' are given for each star. For the region covered, this 
must for iene time to come be a standard catalogue for the prin- 
cipal stars.

cane varies with his position in his orbit, which naturally 
leads to the conclusion that his time of rotation on his axis equals 
the time of revolution in his orbit, as is true for our moon, The 
diameters computed from the m oe mean and minimum bril- 
liancy are 574, 486, and 307 miles
