This is the second edition of a volume which has already proved its value. It is a product of the Fountain Hospital, being written by Dr. Hillard, the former superintendent, and Dr. Kirman, with the assistance of four colleagues, one of whom, Dr. Crome, is consultant neuropathologist to the hospital. The book is tailored to the British scene in its historical review and in the survey of facilities for the care of the retarded, but it can be read with profit and interest by all concerned with the retarded child.
