 antagonistic to my views on species. I well knew this would 

 be the case. I must freely confess, the difficulties and objec- 

 tions arc terrific ; but I cannot believe that a false theory 

 would explain, as it seems to me it does explain, so many 

 classes of facts. Do you ever see Wollaston? He and you 

 would agree nicely about my book 1 — ill luck to both of 

 you. If you have anything at all pleasant for me to hear, do 

 write ; and if all that you can say is very unpleasant, it will 

 do you good to expectorate. And it is well known that you 

 are very fond of writing letters. Farewell, my good old 

 friend and enemy. 



Do make a note about the hippopotamus. If you are 

 such a gentleman as to write, pray tell me how Torquay 

 agrees with your health.

2 Asa Gray (1810-88) was born in the township of Paris, Oneida Co., 

 New York. He became interested in science when a student at the Fair-

 of the duties of teaching and of the active direction of the Gardens, but 

 retained the Herbarium. Professor Gray was a Foreign Member of the 

 Linnean and of the Royal Societies. The Flora of North America (of 

 which the first parts appeared in 1838), Manual of the Botany of the 

 Northern United States, the Botany of Commodore Wilkef South 

 \c Exploring Expedition are among the most important of Gray's 

 systematic memoirs ; in addition to these he wrote several botanical 

 text-books and a great number of papers of first-class importance. In
