          Tuesday Morning.


 My Dear Friend 


 I hear nothing from you whatever, nor have I any parcel 
 from you, tho' Holton has been here, pretty direct from Princeton. 
 I hope my parcel, sent thro' [through] W. & P. [Wiley & Putnam] reached you safely. 


 I have now done the Scroph's [Scrophulariaceae], excepting the Gerardieae, 
 for which I await your material. The Pediculariae, 
 Veronicae, &c. it will not be worth while to send me. I can collate 
 them when I come on in the autumn. But the Hydrophyllaceae
 & Hydroleaceae, I want now very much. I have 
 got on pretty slowly, tho' I work hard & constantly. 
 I must keep at it. Send also the Gentianaceae, if you please.


 I got the other day specimens of Lobelia Cardinalis with 
 rose-colored flowers, from Plymouth. 


 I have a copy of Dr. Wyman's book on ventilation, addressed 
 to you by Dr. W. [Wyman], which I will send by next parcel. 


 I understand now the structure of the fruit of Echinocystis.
 It harmonizes the view that Lindley adoplts, & that 
 of Arnott, which in fact are much the same thing, differently 
 expressed.


 In haste Yours ever
 A. Gray
