          P.S.  I forgot to say, that I got Mr. Dobson to send to New York
 for Dr. Gray's work on the Cyperaceae - & that he received for
 answer it could not be found.  Will you be so good as to 
 cause the work, as far and as fast as published, to be 
 sent to Philadelphia for me, care of Mr. Dobson, No. 108 Chesnut Street?
 Perhaps Dr. Gray, himself, will do me the favor to have it sent
 as above.  Mr. Dobson will advance the subscription money 
 as fast as he received the work for me.  I am very anxious
 to get it as soon as possible.
