206 LIFE OF BENJAMIN SILLIMAN. 



London he was ever present at, was the one at which I 

 read my memoir on the Hylaeosaurus, (afterwards published

 towards me, that at the close of my address, he loudly ap

 him ; and look forward with impatience to the more full 

 detail of his opinions and observations

 in the year to that object, especially as it is always to me 

 an interesting employment. I am very sorry that "the 

 prospect of ever being better becomes less and less." I 

 earnestly hope that you may prove in an error, and while 

 you exhibit so much mental energy as to carry forward 

 elaborate works, demanding much thought, wide study, and 

 graphic skill, I cannot give you up, but will feel some con 

 fidence that the infirm body which holds such a mind, may 

 yet rally and thro\y off its load of infirmity. In my last, 

 I think it was, I inquired somewhat more particularly as to 

 the nature of your complaint, inquiries prompted, not by
