Brady Memorial Foundation, which was established June 15, 1914, by members of the family of the late Anthony N. Brady to enable the University to declare operative the agreement for an alliance between the New Haven Hospital and the Yale School of Medicine. In addition to the pledge of endowment for this purpose, the donors erected for the University on the grounds of the Hospital a clinical and pathological laboratory, and have since, through additional gifts to supplement the income of the Memorial Foundation, made possible the publication of this and other works by members of the faculty of the School of Medicine at Yale. Our grateful acknowledgment is due the Staff of the New Haven Hospital, especially the members of the Department of Medicine, for their hearty co-operation and for the use of the clinical notes. We also wish to thank the members of the Medical Corps of the United States Army who were stationed at the Yale Army Laboratory School while the work was in progress and who aided in many ways:—Colonel Charles F. Craig, Captain R. A. Lambert, Lieutenants C. A. McKinlay, Frederick Parker, Jr., Ellis Kellert, Henry R. Muller, and J. H. Globus. ------------------------------------------------------------------------ TABLE OF CONTENTS Page Introduction 9
