The " Toner Lectures " (of which the present issue is the tenth) 

 have been instituted at Washington, D. C, by Joseph M. Toner, 

 M. D., of this city, for the promotion of medical science. With this 

 object the founder has placed in charge of a Board of Trustees, con- 

 sisting of the Secretary of the Smithsonian Institution, the Surgeon- 

 General of the United States Army, the Surgeon-General of the 

 United States Navy, and the President of the Medical Society of 

 the District of Columbia, a fund, " the interest of which is to be 

 applied for memoirs or essays relative to some branch of medical 

 science, and containing some new truth fully established by experi- 

 ment or observation." .

 Smithsonian Institution, as falling legitimately within its funda- 

 mental purpose, " the increase and diffusion of knowledge among 

 men." The series of "Toner Lectures," published by the Institu- 

 tion iu pamphlet form, is as follows :
