All the ills to which the flesh is heir will be treated, at least verbally, during the annual convention of the Southern Medical association which opens at the Municipal auditorium today and continues through Friday, and New Orleans physicians will have their place as foremost on the convention stage throughout today, climaxed by a public meeting at 8 p. m., when Dr. Lucien Le Doux will preside...Most interesting to the layman among the hundreds; of exhibits which fill the first floor of the auditorium are two which are being conducted by William P. Diduseh, one of which was sent by Dr. Hugh H. Young, and the other by Dr. Os-wald S. Lowsley, both of New York. -- First Display of Kind --Dr. Young's exhibit shows the first display in the history of American medical science on hermaphroditism, and is featured by pictures of the patient before and after an operation in which one-third of the adrenal glands were removed in order to change the apparent sex of the patient from male to female. The second, that of Dr. Lowsley, is a pictorial description of the latest technique for the cure of impotency, in which the physician has removed fatty substances from muscles and allowed them to work normally. However, Mr. Didisch said, a large percentage of impotency is psychological in origin, and therefore not subject to the work of a surgeon. Virtually every type of disease is included in the exhibit. One depicts the progress of the strange disease known as "rat-bite fever," and is conducted by Dr. Roy S. Leadingham, Atlanta. Six cases of the disease are traced through the, pictures. -- TVA Display -- Interesting also is the display being conducted by the Tennessee Valley authority, in charge of Dr. J. A. Crabtree, assistant director of health and safety of the authority, who states that 34 percent-of the Negroes and eight percent of the white applicants for work with the organization are infected with syphilis,
