handbooks. Those investigations which have been concerned with morphological pathology have very largely had origin in the routine diagnostic material, and this has been partly true of research in experimental pathology.
Grants from extramural sources have supported some of the more ambitious research programs. Among the more important grants have been those from the Pease Laboratories, Inc., for investigation of the toxicity of aluminum compounds, from the Committee on Research in Syphilis, Inc., in support of studies on the lesions of latent syphilis and on the demonstration of spirochetes in tissues, from the American Medical Association for a study of the fish tapeworm (Diphyllobothrium latum) in the Great Lakes region, and from the A. C. Barnes Company, Inc., for an investigation of argyria.
Three doctoral dissertations had been presented from the Department of Pathology by the end of June, 1940:
George R. Herrmann, "Electrocardiography and Cardiac Pathology with Especial Reference to Ventricular Preponderance," 1921-22.
Richard E. Olsen, "A Study of the Granular and Atypical Forms of Spirochaeta Pallida in Tissues," 1930-31.
Frank P. Mathews, "An Experimental Investigation of Lechuguilla (Agave lecheguilla) Poisoning," 1936-37.
Twenty-nine students had also received master's degrees in pathology from this department by 1940.
In 1902 reprints of all papers which had been published from the Department of Pathology since Warthin had joined the staff were bound as Volume I of a series entitled Contributions from the Pathological Laboratory. Subsequent volumes have appeared at irregular intervals as material has been available. Volume XIX contains the papers which were published in the period 1937 to 1940. Copies are distributed to the more important medical libraries over the world and also to other pathological institutes in exchange for their own contributions.
Institute for law-enforcement officers. — As might well be expected, those public officials who are charged with responsibility for the investigation and prosecution of criminal acts have frequently sought the aid of the staff of the Department of Pathology and have called on them to perform necropsies, to secure materials for submission to toxicologists, and to make microscopical examinations and photomicrographs of human tissue, and of objects thought to have possible evidential value. In addition, the staff has almost constantly acted in an advisory capacity, in medical matters, with the State Police and other official agencies. Thus, the staff of the Pathological Laboratories has been concerned in the investigation of many notorious homicides in this state.
As the value of scientific technology in the study of crime became more apparent to public officials, there developed a demand for instruction in this field with requests from individual judiciary and police officers reinforced by formal resolutions of various organizations. In March and April, 1934, the first Institute for Law-Enforcement Officers, organized under the auspices of the Extension Service of the University, was held in the East Amphitheater of the West Medical Building. A program of sixteen lectures and four discussion periods was provided. Professor O. W. Stephenson, of the Department of Education, and Dr. Herbert W. Emerson, of the Hygienic Laboratory, aided in the organization of this and the succeeding institutes, which were held in 1935 and 1936. Detailed programs with the personnel of the committees in charge were printed. With the development of increased
