Prof. Alessandro Ghigi, University of Bologna, Italy Prof. R. C. Punnett, Cambridge University, England Prof. Ernst Mangold, University of Berlin, Germany Prof. L. F. Rettger, Yale University, New Haven, Connecticut, U.S.A. Awards The Borden Award for distinctive contributions to poultry science advancement was awarded to Dr. Herman J. Almquist, Associate Professor of Poultry Husbandry in the College of Agriculture, University of California, Berkeley, California. Dr. Almquist was given this award as a result of his work along three lines as follows: (1) In the field of egg quality, developing a number of measures used in the determination of market quality of eggs and also determining several causes for poor egg quality. (2) The discovery

The present report is concerned with investigations of certain seasonal rhythms in the domestic fowl. Under conditions of full feeding and fast, seasonal rhythms in body-heat production, respiratory quotient, calorigenic action of feed, body temperature, and heart-rate were studied in relation to egg production. Heat production during fast increased simultaneously with increasing egg production, and began to decline before egg production began to decrease; but the time curves of fasting and normal heat production appeared to be more closely related to the time curves representing total energy output
(energy gained as body fat plus energy converted into egg material), than to those of egg production alone. (Body weight gained by mature hens was assumed to be fat.) A technic was developed for recording heartrates of hens in darkened respiration chambers at 30°C. Heart-rate determined in this way was much lower than has been supposed. A positive correlation, based upon a great many determinations was found between heart-rate and heat production in fowls, but the correlation coefficient was not high. A multi-chamber respiration apparatus of the Regnault-Reiset type was designed and built for use in these experiments. It is generally recognized that seasonal rhythms in egg production seem to be related to length of day. The experiments reported here indicate that body heat production appears to be closely related, not to egg production alone, but instead to the total energy output of the fowl.

Meeting
It was voted by the Association to hold its 1940 Annual Meeting at Cornell University, Ithaca, New York. Cornell University News. An exchange has been arranged in the Department of Poultry Husbandry whereby Professor L. E. Weaver goes to the University of Hawaii for ten months beginning September 1, 1939, and Professor C. M. Bice of the latter institution will be at Cornell for the same period. Mr. Clyde Mueller (B.Sc, Kansas State, 1939) and Mr. Dean Jones (B.Sc, Purdue, 1939) have been appointed research assistants in the Department of Poultry Husbandry. Dr. R. K. Cole (Ph.D., Cornell, 1939) has been added to the staff of the De-

partment of Poultry Husbandry with the rank of instructor. He will continue his work on genetic resistance to fowl diseases. Dr. W. F. Lamoreux has been appointed Assistant Professor, and Dr. G. O. Hall has been appointed Associate Professor in the Department of Poultry Husbandry. Alabama Polytechnic Institute News. Dr. Paul Sturkie (B.S., and M.S., Texas A and M College, 1935; Ph.D., Cornell University, 1939) has been appointed Associate Professor of Poultry Husbandry at Alabama Polytechnic Institute. Dr. Sturkie will be working in the field of poultry genetics. Mr. John Goodman (B.S., and M.S., Ala. Poly. Inst., 1934), who has been in charge of poultry work at Berry College, Mount Berry, Georgia, has been added to the teaching staff of Alabama Polytechnic Institute.
