Abstract
THIS is the third of a series of text-books recently prepared by Prof. Young for use in schools and colleges of different grades. The two previous ones have already been noticed in NATURE (vol. xxxix p. 386, and vol. xli. p. 485). The present work is described on the title page as “a brief introductory course without mathematics, for use in schools and seminaries.” The three books have much in common, and each one has many good points. We cannot help feeling, however, that the steps between them are too small. Almost exactly the same ground is covered by each, and they differ chiefly in the amount of previous knowledge assumed. But the acquaintance with mathematics required for a thorough comprehension of the “General Astronomy” is by no means great, and even for the “Lessons” a certain knowledge of geometrical principles is essential. If we must needs have three books, the “General Astronomy” contains too little, and the “Lessons”—a book of some 350 pages—contains too much.
Lessons in Astronomy.
