Part 1 deals with "feebleness of growth" and is a defense of the following three theses: "1. Feebleness of growth is proportional to the intensity of the nocivity. 2. Feebleness of growth is proportional to the rapidity of the growth of the individual and its parts (law of the vulnerability of fastgrowing cell groups). 3. Feebleness of growth is characterized by enhanced sensibility and enhanced fatigability."
Part 2 is devoted to congenital dwarfism, with a lengthy and profusely illustrated discussion of dysostosis cleido-cranialis and brief chapters on anencephaly, achondroplasia and mongolian idiocy. All of these conditions are considered as caused by smallness of the amnion becoming operative at various periods of fetal life.
The philosophic and thoroughly logical, as well as original, treatment of obscure developmental conditions makes
