3. Annals of the Astronomical Observatory of Harvard Col- 
lege. Vols. VIII and X.—The first seven volumes of the Annals 
of the Astronomical Observatory of Harvard College contained 
the results of the work done under its first two Directors, W. C. 
Bond and G, P. Bond. 
Three catalogues gave the observed places of 16,084 stars 
observed in zones between the equator and 1° N. declination. 
The great comet, of 1858, the nebula of Orion, and spots on the 
sun, each filled a volume, and the planet Saturn filled one part of 
a volume. The second part of vol. IV has not yet appeared, but 
is in course of publication. The eighth volume contains in its first, 
part an historical account of the Observatory from 1855 to 1876, 
and is richly illustrated by engravings of the instruments and 
apparatus of the Observatory. The second portion consists of the 
“ Engravings from the Observatory of Harvard College,” which 
has been furnished separately to subscribers, and has been hereto- 
fore noticed in this Journal, ey are thirty-five in number (mak-

with three catalogues: Ist, of 289 primary stars, being t

Sunction of the ae motions of a Sun and oie ; by G. W. 
Hit, Cambridge, 1877. 4°, pp. 28.—The motion of the lunar 
ce. ee as observed does not agree with any of those computed 
Y theory within the limits of error of the observations. This

on the mean motions of the sun and moon, with a degree of accu- 
Tacy that shall leave nothing further to be desired.
