Through the courtesy of Mr. Morrison Carnegie, the 

 opportunity to collect animals on Cumberland Island was 

 afforded us. This research was extended to include the 

 organs of eighteen bulls and steers that were collected in 

 Jacksonville, Florida. These animals were found to be free 

 from goiter and more nearly like animals in the wild state 

 than were the domestic animals in Ohio that we have also 

 studied. 



Dr. Herbert C. Clark, director of the Gorgas Memorial 

 Laboratories in Panama, sent a large amount of material 

 and data from Panama to Cleveland, including memoranda 

 on 525 monkeys, sloths, tapirs, armadillos, ant-eaters and 

 collared peccaries, as well as on small rodents and many 

 domestic animals. This material was studied in the Research 

 Laboratories of the Cleveland Clinic Foundation in collabo- 

 ration with Daniel P. Quiring, Ph.D., director of the Divi- 

 sion of Anatomy. 



In the course of these researches there were brought alive 

 to the laboratory alligators, crocodiles, lions, tigers, bears, 

 chimpanzees, some from zoological gardens and others 

 imported directly. 



It was because we believed that the source of the many 

 so-called "energy diseases" of civilized man lay in the 

 pathologic physiology of the energy-controlling system, in 

 particular that sector designated the "abdominal brain" 

 or "power station" of the sympathetic system that is, the 

 celiac ganglia that an expedition to Africa was organized 

 in 1935. 



The members of this expedition were Dr. Daniel P. 

 Quiring, Mr. Arthur B. Fuller, Dr. W. Harrison Carr, of 

 England a guest, Mrs. Crile, and I. 



Through Captain J. Raymond Hewlett, our hunter, and 

 Mr. Bryan Cooper, a laboratory was established in the Rift 

 Valley, in Tanganyika, at a latitude 2 south of the equator. 

 Here perhaps a greater concentration of wild life abounds 

 than in any other known region of the earth, and here in the
