This useful and interesting book consists of the proceedings of one of the Developmental Biology Conference Series held under the auspices of the National Academy of Sciences and the National Research Council. The conference was held at the Roscoe B. Jackson Memorial Laboratory in Bar Harbor, Maine and was attended by about 20 authorities from the United States and Europe.
One means for study of environmental influences on development consists of an examination into the causes of morphologic abnormalities. The book begins with some consideration of such defects.
