Advanced Physiography

Abstract

TEACHERS have long felt the need of a good text-book on advanced physiography, and will no doubt fully appreciate the little book before us. Mr. Gregory's twelve chapters on the astronomical side of the subject form an admirable supplement to his now well-known “Elementary Physiography.” This part of the book is treated in a very practical manner, and the text is at the same time remarkably free from errors; one mistake, however, is in placing β Cassiopeiæ amongst the bright-line stars instead of γ Cassiopeiæ. The various astronomical instruments are described in a clearly-written and well-illustrated chapter, which should prove extremely useful to students who have not the advantage of seeing and using the instruments for themselves. In all the most recent discoveries the book is well up to date; in the chapter on “Stars and Nebulæ” a racy account is given of the discovery, observations, and probable origin of the new star in Auriga. The author writes with a practical knowledge of his subject, and has done as much justice to it as the limitations of a text-book allow.
