Dear Engelnann, 



1 received your letter of Jan. 15 on the 2?th of the sarae 

 month, but hesitated. with a reply in order to ans wer raore defi - 

 nitely. I sent your manuscript imnediately to Prof Torrey in N. 

 Y. and received it back a fei-r dnys ?^o with the reply that he has 

 read thronen two parts and did not want to change anything in the 

 text t but that he wants to take the liberty to make the f ollowing 

 reraarksi 1) Larrea glutinöse be most llkely Larrea nexicana of 

 Morricam, described and illustrated in a publication to which Dr. 

 E. has access. 2) Geraniun pentag: ynum seems to hin to be Gera- 

 nlura f renontil (Torrey of Fren. 2 Reno^t) . I have added these re- 

 marks at the end of your manuscript. Mr. Nuttal, so Torrey writes 

 to rae, is presently oocupied with the description of the plants 

 which Mr. Garabi e collected in (?) in New Mexico, and H there 

 is danger of cross-f ixing with dr. Eng. Torrey asked me there- 

 for to send inmediately several copies of ny botanical appendix, 

 which I will not delay. The printing of my manuscript began only 

 on the 5th of this month and will probably be finished by the end 

 of the month. Up to now only 2 print-sheets have been printed. I 

 take care of the second proofreading (verbat im: correction) , and 

 the botanical part I shall take otfer rayseif and as your manuscript 

 is very l&gible, good proofreading will not be amiss. Of the Botany 

 I shall have 50 copies printed in the special desired way and mail 

 them to you inmediately after printing. I have ordered also 50 co- 

 pies of the maps for myself. By nowjhasjthe barometric prof ile|jal- 

 so been corapleted, and I expect daily a corrected proof of it from
