The "Toner Lectures" 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 jilaced in 

 charge of a Board of Trustees, consisting 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 experiment or observation." 



The publication of these Lectures has been undertaken by the 

 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 in pamphlet form, is as follows; and they are also included in 

 the "Smithsonian Miscellaneous Collections."
