Abstract
THE problems of the diurnal rotation, meridian observations, the motion of the moon and planets, precession, nutation, refraction, etc., are dealt with in quite an elementary manner in the work under notice. The chief new feature is an interesting account of ancient Indian astronomy. The book is, unfortunately, greatly in need of revision, misprints, misspellings, and other errata being numerous. Some of them are likely to cause serious misconceptions; thus, the moon's distance is given as 23,800 miles, both on pp. 102 and 117. On p. 146 the distance of Europa from Jupiter is given as 9400 miles; on p. 538 the periodic time of a planet is stated to vary as r3. It is difficult to suppose that the proofs were read with any care.
