ELIA5 DIFFENBACH. 



Elias Diffenbach was a compositor in the printing 

 office of Collins & Company. His vocation injured his 

 health and he was threatened with consumption. Dr. A. 

 W. Chapman wrote from Apalachiola, Florida, that the law 

 allowed him a deputy whose duties were nominal and 

 whose salary would be $1200 a year. He wanted a botanist. 

 Charles E. Smith, of Philadelphia, named Diffenbach, who 

 at first accepted and afterwards declined. Mr. Smith urg-ed 

 him to accept, saying : "If you were a rich man you 

 would spend a thousand dollars in going to Florida for your 

 health. Here you are offered a |1000 if you will go." He 

 finally declined, and Saurman went in his place. Diffen- 

 bach then went to Illinois, where he had a brother, a 

 druggist, with wdiom he worked, the next year dying of 

 consumption.
