Elementary Biology. By T. Jeffery Parker. (Macmillan and Co.)—A well-written

and certainly instructive text-book this.

Analogies and comparisons are pointed out, and the reader is persuaded to be observant; and this is a step in the right direc- tion, and distinctly better than the tendency to concentrate everything on profound histological research. The book is well illustrated, and plenty of practical advice is given, and couched in a more conversational style than is usual in such works.
