This book is designed especially for beginning students in microscopic work on animals, and describes in detail the various methods and technic of the elementary processes such as killing, hardening, preserving, staining, sectioning and mounting. Several appendices deal with the theory of the microscope, the use of stains and reagents, collecting material for an elementary course in zoölogy, etc. Directions for blood work and for bacteriologic technic as well as embryologic methods are given so that while the trend of the book is toward zoölogy proper, the medical student will find it very useful as a guide to microscopic work. A feature for which the book is to be highly commended is the clearness of the directions which make it easy for the student to follow the methods. It is well illustrated with pictures of instruments and apparatus.
