F. CONRAD Koen Professor of Plzysiologiml Chvmimfy HARRY G. WELLS Prafznvsur and Chairman, Department of Pathology THE BIOLOGICAL SCIENCES . . . ANATOMY . . . PATHOLOGY . . . PHARMACOLOGY . . Investigations in the Anatomy De- partment Were carried out under the di- rection of Dr. Bensley and Dr. H. H. Donaldson. Dr. Bensley, chairman of the department, was primarily interested in microscopic structure and function of the glands derived from the alimentary tract. Dr. Bensley has in the past de- veloped methods of dissecting out the islets of Langerhorn for the study of in- sulin production. He continued his stud- ies on the technique of histological ex- amination of the digestive glands. Dr. Donaldson devoted his main research to the embryological development of the nervous system. Under the direction of Dr. Harry G. VVells, nationally acknowledged author- ity on pathological technique, the depart- ment of Pathology has extended its field of research. The Department col- laborated with the Otho S. A. Sprague llemorial Institute and the National Tuberculosis Association in their re- spective research studies. lliss Nlaud Slye, under the auspices of the depart- ment and the Sprague Institute, investi- gated the relation between heredity and the occurrence of cancer in a given fam- ily. No definite results were obtained but considerable light was thrown on the problem as a result of this Work. Dr. Esmond R. Long, the outstanding au- thority on tuberculosis in the country, in conjunction with the National Tuber- culosis Association and Dr. Florence Seibert studied tuberculosis from the standpoint of the relation of its proper- ties to the natural defense mechanisms of the body. The Department of Physiological Chemistry and Pharmacology under the direction of Dr. F. Conrad Koch, con- tributed an unusually large amount of valuable information on the reactions of the body from the chemical standpoint. Dr. Hanke of the department investi- gated metabolism of food in mammals. Dr. Koch directed studies on the assay of the male and female sex hormones. Further work in the department includ- ed a chemical study of the hormones of the pituitary body and the isolation and analyses of the proteins in citrus seeds and nuts. Page I4

I 1 I Y CHARLES J. QHAMEERLAIN ,Professor Emzfrztus of Boiany ALFRED E. EMERSON flssoriate Praferxor of Zoology THE BIOLOGICAL SCIENCES ...CYCADS . . . TERMITES . . . EDEMA . .. George K. Link, of the Department of Botany, spent the past year investigating the pathological features of virus diseases and the relationship of those diseases as illustrated through experiments with plants. Professor Chamberlain continued his collection of the existing cycads. These plants, one of the last relics of a past geological age, have been calcu- lated to be about five thousand years of age. Dr. Chamberlainls collection. housed in the New Botany Building, is the largest of its kind in the world. Dr. F. R. Lillie, chairman of the De- partment of Zoology, studied the biology of sex in fowls which were carried on in close collaboration with the Department of Physiological Chemistry. Dr. H. H. Newman extended his studies on twin- ning to man. One of his most interest- ing projects concerned an attempt to find the degree of similarity between identi- cal human twins which were separated in infancy and reared apart. Dr. A. E. Emerson focused his studies upon the biology of the highly social termites with the view of analyzing their ecological adjustments. Dr. Robertson studied the cause of pneumonia and succeeded in producing lobar pneumonia, experimentally. Dr. Hastings' research dealt with the cause of edema and the factors concerned in bi- ological oxidation. Experiments showing the influence of ultra-violet rays on the tubercle bacillus were made by Dr. Bloch. in Iii OswAi,o H. ROBERTSON Proffuor and Acting Qhqzrrnan Df'par11nmt of Ilflcdzrzrze Page 13'

U an ANTON 1. CARLSON Profmvor and Chazfman, Dej1artrm'nt of Physiology HARVEY CARR Professor' and Chairman, Department of Psychology THE BIOLOGICAL SCIENCES . . . PHYSIOLOGY. . . PYSCHOLOGY . . . SURGERY. . . Dr. Carlson, physiologist and eminent authority on the function of the digestive tract, continued his studies on the diges- tion and motility of the large intestine as observed in animal experimentation on dogs. He found that extirpation of the pancreas incre-ases to some degree the mo- tility of the colon. Dr. Luckhardt, who discovered the anaesthetic power of eth- ylene, extended' his research studies on this gas in an attempt to make it safer for surgical use. The value of this dis- covery can hardly be measured at the present time. University Psychologists through their brilliant research, have advanced their department to a position unsurpassed by any other group of psychologists in this country. Dr. Harvey Carr and Dr. A. G. Bills through the medium of tests given throughout the country studied learning, space perception, and mental aptitude. Professor Thurstone in his investigations of racial feeling in social attitudes devel- oped several interesting factors. In the Department of Surgery re- search was developed along several inter- 1 esting and vitally important lines. Dr. Bailey studied the changes brought on by brain tumors and the resultant factors as indicated by changes in the body. Dr. L. Rothman investigated the develop- ment of nearsightedness and Dr. C. Dev- ney studied the refraction curve in my- opia or nearsightedness. Peucivat BAILEY Proj'L'.uor of S1U'gL'l'y Page I5
