Dr. Lowrey has divided his paper into three parts corresponding to three historical periods in the development of child psychiatry. In the first period (1846–1909) interest was centered primarily on the mentally defective and in the establishment of clinics and schools for their care and training. In the second period (1909–1919) begins the study of other problems of children, especially those of delinquents. The third section brings up to date the extension of these studies and the establishment of clinics, special schools, institutions, children's wards and out-patient departments for the treatment of childhood disorders, and training centers for those working with children's problems. The paper gives a comprehensive survey touching on all aspects of the development of child psychiatry with one notable exception—there is no discussion of the important contributions of psychoanalysis to this field, and there is only one brief reference to Freud.
