Dr. A. F. A. King. Dr. King was professor of obstetrics in Colum- 

 bian (now George Washington) University, Washington, D. C, and a 

 well-known Washington physician. He was a man of unusual mental- 

 ity, and as early as 1883 published in The Popular Science Monthly 

 an extended article in support of the idea that malaria is carried by 

 mosquitoes. His array of reasons was so great and his argument so 

 convincing that his paper has been considered the very strongest of any 

 on the carriage of disease by insects, published prior to the actual proof. 

 He died December 13, 1914, in Washington, D. C.
