The " Toner Lectures" have been instituted at Washington, 

 D. C, by Joseph M. Toner, M.D., who has placed in charge of 

 a Board of Trustees, consisting of the Secretary of the Smith- 

 sonian 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 Colum- 

 bia, a fund, " the interest of which is to be applied for at least 

 two annual memoirs or essays relative to some branch of medi- 

 cal science, and containing some new truth fully established by 

 experiment or observation."

 edge, they have been accepted for publication by the Smith- 

 sonian Institution in its " Miscellaneous Collections."
