 My Dear Doctor


 I have yours of the 24
 & 28th. I have just forwarded 
 the mss. [manuscript] to Capt. [Captain] Humphrey's
 (also Beckwith's drawings); but 
 in the proofs I will make the 
 corrections required about the
 Eriogona.


 I received the two checks, 
 have handed to Sprague his 
 for $125. I shall have no 
 difficulty in getting them cashed 
 through our bank & realizing 
 the proceeds in a few days, probably 
 without any discount whatever. 
 So in my next I can send 
 you your portion. But in 
 what form? To get a draft 
 on New York I must get it
 in Boston. It will cost only 25
 cents at most.
