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'

lj D THE BIOLOGICAL SCIENCES FRANK R. LILLIE Dean of Biologital Sciences As in the past, the biological scientists at the University continued their excep- tional worlc both in the classroom and in the laboratory. Much research was done in the past year as was seen by the work of Chamberlain in Botany, Carlson in Physiology, Wells in Path- ology, Carr in Psychology, and Bailey in Surgery. The various investigations made by the departments under the Bi- ological Division were of significance to both the layman -and scientist. The Biological Sciences, headed by Dean Lillie, adapted its work to suit The New Plan. The Division required the student to take a majority of Work in one department with the related work to be approved by the department of spe- cialization. The general course offered in the Col- lege was conducted by the most compe- tent men of the Division. The course was concerned with the variety and re- lationship among living -organisms, study- ing plant and animal Icingdomsy the dy- namics of living organisms, emphasizing the physiology and psychology of man in health and diseaseg organic evolution, heredity, and eugenicsg and ecology, studying the relation of living organisms to their environment and to each other, as Well as a consideration of the problem of social organization in lower organisms.

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
