THIS book is intended for the use of pupils who have already had a certain amount of biological training in school. It covers a very great deal of ground in a very superficial manner, but in the hands of a capable teacher it should serve as a good foundation for an extremely interesting course of general biology. It commences, in what we conceive to be a very logical manner, with a general account of the cell, but the fact that this occupies less than one page is typical of the superficial method of treatment. A few unicellular organisms are then dealt with, chiefly from the physiological point of view.
