WE have at the present time several very excellent text-books of physiology in English, adapted for the various needs of different classes of students. And to prevent these being inconveniently increased, it is a matter of tacit agreement amongst teachers of physiology that it is undesirable to afford a welcome to any new text-book, unless it has itself the highest claims to recognition. These claims may be based either upon some novel method of treatment of the subject, or upon the impression on the work of an author's high personal authority. A Manual of Physiology. By G. N. Stewart (London: Balliere, Tindall, and Cox, 1895.) Physiology. By A. Macalister “Manuals of Science Series.” (London: Society for Promoting Christian Knowledge, 1895.) Elementary Physiology. By J. R. Ainsworth Davis (London: Blackie and Son, 1895.)
