A Glossary of Biological, Anatomical, and Physiological Terms. By Thomas

Denman. (Griffith and Farran.)—The utility of this book is manifest. The nomenclature of science is continually in- creasing, and an explanatory index of this kind becomes a necessity. Here is but one province, so to speak, and it has a vocabulary almost as large as a language,—between two and three thousand terms, we should calculate. It is to be regretted that the derivations are not more correctly given. They should have been revised by a classical echolar. In that case, we should not have Kotulos for Kotttle, pseudos for pseudes, the non-existent formptoo to account for " ptosis," or the derivation of " Xanthocroi" from " xanthos, yellow, auburn, and ehronta colour," instead of chros, the skin.
