CONDENSED RESULTS OF DIVISION C OF POT EXPERIMENTS 



Colonel William C. Gorgas, Surgeon-General of the United States Army, received 

 the honorary degree of Doctor of Science from Princeton on June 16, and of Doctor 

 of Laws from Yale University on June 17. In presenting him for this honor at Yale, 

 Professor Cross spoke as follows: 



"WiUiam Crawford Gorgas, Surgeon-General of the United States Army. It 

 is needless to rehearse the career of General Gorgas. As chief sanitary officer of 

 Havana, he entered into a close fight with yellow fever and drove that disease from 

 the Cuban capital. As medical director of the Panama Zone, his appHcation of the 

 lessons of science to practical hygiene and sanitation made possible the completion 

 of an immense engineering project. In recognition of his splendid achievement, he 

 has been honored at home and abroad by degrees, medals, and membership in 

 scientific societies — and most impressively by his recent call to South Africa to im- 

 prove the sanitary conditions in the mining district of the great Wit watersrand. 

 To General Gorgas, as to few others, has been allotted the extreme distinction of 

 having the story of his achievements become a part of current history and to com- 

 mand the admiration of the civilized world. Of old, this honor came to conquerors 

 who left blood and slaughter in their trail; it has come to General Gorgas for the 

 unnumbered lives he has saved."
