 is. I was born in Frankfurt a.M. ( on the Main. River, E.D.)in 1809 and

 in St, Louis, where, as you know, I live as a doctor. I bep-an my botani- 

 cal studies already as boy by pref erence» and d.o as rauch in. this science 

 as my profession permits.

 but continue to study them as opportunity permits. Since several years 

 I have bee^ occupied intensively with the study of the Conif ers t and 

 f lower in$ and. fruit ing srecimens of them from Mexico, of which I possess 

 already some from Dr. Gregpr, would be most welcome II would love to see
