Obituary. 



Dr. Silas Weik Mitchell, gifted alike as investigator, phy- 

 sician, novelist, and poet, died on January 4 in his eighty-fifth 

 year. Few men of any nation or time have been able to accom- 

 plish so rare a work in physiology and medicine and at the same 

 time to take a place in the first rank of men of letters. His inter- 

 ests were as varied as his vigor was unlimited, and his activity 

 continued till near the close of his long life. He will be mourned 

 alike by a circle of friends as broad as the nation and by a host 

 of grateful patients whom he helped to overcome their nervous 

 ailments.

 work was varied and important, extending over both mathematics 

 and physics ; the phenomena of magnetism were of particular 

 interest to him.
