Abstract
THE determination of the plane of bilateral symmetry is one of the most important events in embryonic development, since it sets the framework of that essential cytoplasmic heterogeneity which alone makes it possible for one and the same genotype to control the differentiation of many types of tissue. In some eggs (of which insects provide clear-cut examples), the bilateral structure is built into the ovum during its maturation within the ovary. In others, among them apparently all vertebrate ova, bilaterality does not become visible until after fertilization, and much research has naturally been directed to discovering the factors to which it is due. The Amphibia have, here as in so much of experimental embryology, provided the most favourable material for study. A long series of observations and experiments on this group by Prof. P. Ancel and P. Vintemberger, which have ndw been brought together in book form, seems to go far towards providing at least an interim conclusion, which may last some time before it is superseded.
