Between the Planets The Story of Variable Stars Galaxies

Abstract

THESE three volumes belong to the well-known series of Harvard Books on Astronomy. The first and second were published in 1941, the third in 1943 ; reprints of all three have been required, and some additions have been made to the second. The Harvard College Observatory is to be congratulated on its enterprise in arranging for the publication of a series of eight books, all by members of its staff, which together provide a comprehensive and up-to-date survey of astronomy. Each book is written by an authority in its particular field, is abundantly illustrated, and is well printed. The series has gained a well-merited success. Though intended primarily for students, teachers and amateurs, the books are useful also to the working astronomer for reference purposes, as recent developments in the respective fields are dealt with.
