^T. 24.] TO JOHN TORREY. 51 



engraving, now in the hands of the artist, will be 

 transmitted to you by the earliest opportunity, 

 also send a little parcel of mosses, nearly all of which 

 were collected in the interior of the State of New 

 York. May I ask you to look them over at as early 

 an opportunity as may suit your convenience, and to 

 return to me the result of your determinations. I 

 do not venture to think that you will find among them 

 anything of especial interest. I very much regret 

 that I am at the present moment unable to forward 

 to you a half a dozen copies of the work of " Gra- 

 minea3 and Cyperaceffi," the number you so kindly 

 offer to take charge of. A few species are wanting to 

 complete further suits of the first volume, but these 

 I hope soon to obtain. Not to permit your kind offer 

 to pass wholly unimproved, I hereby transmit to you 

 three copies of vols. 1 and 2 which are at the disposal 

 of any of your botanical friends who may desire to 

 possess the work. If an additional number of copies 

 should be needed they can in a very short time be 

 furnished. With high respect, I remain, dear sir, 



Yours truly, A. GRAY.

 for I found that close confinement was spoiling my 

 health, so I have been taking quite severe exercise 

 almost constantly, by which I am considerably im-
