Abstract

ALTHOUGH it is the general practice among teaching botanists to combine in lectures the explanation of physiological principles with descriptions of the organs involved, the combination of microscopical anatomy with physiology in a practical book is unusual. In the present instance there is complete separation into a course of microscopical exercises that occupies about three-quarters of the volume, and a set of physiological experiments and deductions. The anatomical course begins with a description of the necessary apparatus for microscopical technique, after which there follows a series of studies of the cell, stem, leaf, and root, nearly identical with the types in Stras-burger's “Botanisches Praktikum,” in so far as these relate to flowering plants. This part of the book is excellent, especially for teachers who wish to become thoroughly conversant with all details and skilled in manipulation. The directions are explicit, the hints on reagents and methods are practical, and the accompaniment of typical illustrations will be found useful. The physiological course does not product such a favourable impression. The conduction of water and salts bulks largely in the foreground, and, seeing that it is an unsolved problem, it would seem more rational to give it less prominence. Generally speaking, the experiments appear to have been chosen rather te demonstrate dogmatic ideas than to serve as exercises practicable for general students.
