Introduction to Discussion

Cornell University, Ithaca, New York

Abstract

Dr. Farner deserves our thanks and congratulations for a very excellent presentation. He has presented us with a general scheme of avian reproduction, and in this case I will exclude chickens from avian reproduction, because Dr. Farner has so well-defined the chicken as "the white rat among birds". Others have called the chicken a zoological monstrosity. On other occasions I have given a spirited defense for the use of the chicken as an experimental animal—mostly at project site visits!

I wonder whether I could see the first of Dr. Farner's slides. I would like to discuss his general scheme and the information that we may supply from some other species that have been used. In the first place I would like to discuss the reception and transmission processing that Dr. Farner has mentioned and mostly here in connection with the photoperiodic response.
