Several years have already elapsed since the authors began pathological studies of poultry diseases. At the present time, they are attempting to clarify the pathogenesis of gout in poultry from a pathomorphological standpoint. A total of 2, 863 chickens were submitted for research and originated from the breeding groups belonging to the G HATCHERY, INC. These specimens had been designated for diagnosis, some having been collected for the purpose of research in avain leukosis. Among these specimens, 45 cases from a total of 67 chickens which avain gout had been certified by pathoanatomical and histopathological investigations were subjected to these studies. The results were as follows : A) The various histopathological phases of avian gout. Not only the serosa but the lesions which can be seen in the various organs are pathologically speaking, simply the result of the disposal foreign bodies. However, from the incipient lesions to the final stage it is characterized by various changes (Figs. 1-12). B) The age distribution and prognosis of avian gout. Much has been written about avian gout in full grown birds ; the results of the present study are derived from the outbreak of the disease in chickens which, for the most part, were presented for authopsy. Moreover, in the case of day old chicks, many cases could be seen where avian gout had reached the final stages (Figs. 9, 11 & 12). C) The relationship between avian gout and fowl species. It was verified that the outbreak of the disease varies according to the species of fowl, but there is room for further research in this field. D) Etiology. The present study does not propose to enter the realm of etiology. However, on the bases of the above mentioned research, the frequency of the outbreak of the disease must be considered a characteristic of the protein and amino acid metabolism in the developing embryo. In brief, as a result of the present histological research, cases of gout in adult birds were found to be few ; whereas in the case of chicks, the disease was prevalent. This is "abnormal metabolism of uric acid during the embryonic stage".
