 Dear Dr. 


 I received your parcel, 
 and as there was no letter 
 I thought you were following 
 it. Now that Engelmann 
 has reached New York, I 
 shall not see you, at least 
 for some days. So I will 
 send you a parcel to-morrow 
 i.e. will return your 
 Acanthaceae.


 As I must do something 
 to help you if I share
 in the pay, I have 
 now given 2� days to 
 the Acanthaceae, and 
 you will see all that it 
 amounts to, when you get 
 the parcel


 To-morrow, before the 
 parcel goes, I shall 
 hope to say what is needful 
 about the Leguminosae & the
