Dear Dr. Hollick: — 1 have delayed replying to your kind invitation 

 to the anniversary dinner of the Staten Island Natural Science Associa- 

 tion in the hope that I might find it possible to accept. But I am reluc- 

 tantly compelled to admit that I am yet physically unfit to go out nights 

 and enjoy evening occasions. 



By careful attention I can manage to get through my day's work, 

 but' by the time night comes I am physically and mentally exhausted 

 and good for nothing. I have not spent an evening out since last April. 



Under the circumstances I can only thank you most gratefully for 

 your very kind and much appreciated invitation, and assure you that 

 were I physically able I would joyously accept. It would give me 

 great pleasure to participate in such an anniversary. 



Wishing the Association long life and great prosperity, I remain 



Sincerely yours, 



W. T. Hornaday.
