Abstract
DR. COUPIN has produced a descriptive account of gamete and zygote formation in the principal kinds of plants and animals, with 112 figures and an index of the names of the plants and animals cited. The matter is arranged according to a scheme explained in the introduction. The first division is made to depend upon whether the zygote is formed inside or outside the body of the organism. In each of these categories we have a series showing isogamy and one showing heterogamy. The further subdivisions depend upon the mobility or immobility of the gametes. So far as possible technical terms have been omitted. Subjects such as nest-building and special mating habits are treated to some extent under the various groups. The information given appears to be generally reliable, but the scheme of arrangement naturally leads to the various types of plants and animals being grouped in a somewhat unusual manner. One result of this is that clenterates are all considered as being forms in which the zygote is produced within the body of a parent animal.
