In the first section of this monograph, on the morphologic basis of mental development, de Crinis includes a report of his studies of the brains of sixty-eight children, showing the growth of ganglion cell dendrites at different ages. The remainder of the book contains no original material, but is a concise presentation of the classic views on the development of mental activities, their deterioration following cerebral lesion and the site and nature of the lesions underlying different syndromes. In the fields of aphasia, apraxia and agnosia de Crinis lays greatest stress on the doctrines of Wernicke; he refers to some of the newer points of view, but briefly and with little critical analysis.
