Nature Teaching on the Blackboard. By W. P. Pycraft, F.Z.S.

Illustrated by Janet Harvey Kelman. (The Caxton Publishing.

Company. 3 vols., Is. 6d. each.)—A large number of plants are described, and spirited drawings full of intelligent appreciation of form illustrate the letterpress. These are a model of how to draw with white chalk on a dark ground when the object is clearness of presentation.
