Potter presented cases of feeble-mindedness in which malfunction of the endocrine gland seemed to play important parts. He demonstrated also a special chart which he had prepared for the occasion which showed the upset of structure and function which accompanies malfunction of the several endocrine organs. In the afternoon of the same day, the group visited the State Hospital for Crippled Children, at West Haverstraw, N.Y. Thanks to the kindness of Dr. J. J. Nutt, Superintendent, the students were shown the principal types of congenital and hereditary defect which caused children to be sent to this hospital for treatment. 6. On August 5, through the courtesy of Dr. George Kirby, Director of the Psychiatric Clinic at Ward's Island, N. Y., Dr. Clarence O. Cheney gave a lecture and clinic, in the first part of which he demonstrated several cases of the so-called "war psychoses." In the second part he showed the relation between the endocrine secretions and certain types of mental disorders. In the afternoon of the same day, the class continued to Randall's Island, where it first visited the New York City Children's Hospital. Dr. John S. Richards, Medical Superintendent, had kindly prepared a reception which enabled the students to examine at first-hand large numbers and a great variety of mentally and physically defective children. They visited also the island's Psychological Laboratory which was recently established. Still later in the afternoon, the House of Refuge on the same Island was visited. Here, under the direction of Superintendent E. C. Barber, opportunity was given to inspect the work of the boys, and to listen to a lecture by the assistant superintendent on the nature of the particular problems involved in handling delinquent boys. 7.

On August 9, the class proceeded to Commack, Long Island, where they hurriedly mapped the village and divided it into ten sections. Each student then proceeded to make a census and an eugenical and historical survey of the territory in his particular district. This study resulted in securing a genealogical and trait record of practically all of the present inhabitants of this village. The next few days were spent in preparing the pedigree charts and analyzing the records secured in the field. 9. On August 11, the class again repaired to Kings Park, where the clinical director had selected a number of cases of patients who came from homes on Long Island. The students examined these patients and studied their hospital records. 10.
