 Dear Doctor


 Don has nearly 2 pages on Cleomella. 
 I have copied all that seems to be of any 
 bearing on the [crossed out: species] question of which species. 
 Mocinno & Sesse's things, remember, often come 
 from North Mexico. But I should think 
 the original Cleomella, is what you call C. [Cleomella] mexicana.
 Pity this was overlooked when the Flora was 
 written, as it makes it plain that we 
 should not have inferred our Cleomella to be
 C. [Cleomella] mexicana. How Hooker overlooked it too! 


 You can readily find Don's paper  in 
 Edinb. [Edinburgh] Journal in New York, in Society 
 Library doubtless.


 Vauquelinia, H. B. K. [Humboldt, Bonpland & Kunth] is not my
 519 & 104. Pl. Gregg. 


 I can find no box long enough to 
 take in Agassiz' drawings. So I must 
 send a number of parcels, or long stout 
 rolls, which I will try to make secure 


 Yours in haste as ever
 A. Gray
