The lectures here included were developed for the New York Academy of Medicine and the Johns Hopkins Medical School. As a pioneer in the organization of education in the field concerned, all that Professor Ryle has to say is of interest to the physician. Among the most interesting of the essays is that dealing with medical ethics and the new humanism, since it provides opinions and information on problems that are today rather controversial. One finds Dr. Ryle saying that the decline in infant mortality can be attributed in large part to general social betterment and the falling birth rate, whereas Sir Stafford Cripps recently gave most of the credit in Great Britain to nationalization of medicine.
