 My dear Sir, 


 I have examined the drawings you have been good enough
 as to transmit to me by express and which I [?] are to you 
 with my thanks.


 In those of Dr Hilgard, there may be superflaities; but with
 one exception, that of Minculus, I do not think there are any
 inaccuracies. As you have more experience than ourselves, 
 and know better what is proper in those things, I repeat:
 Do for the best, I answer for Dr Hilgard and myself. I
 have appended to your own notes my ascent or remarks.


 As to the six pencil drawings, I know nothing about them,
 nor by whom they are made. From the numerous stamens
 of erigonum roseum and other imperfections, it is evident
 that they were no made by a botanist. Having my share
 of responsiblity in the matter, I would not have them, unless
 they are carefully corrected or re-drawn.


 The cusenta ought to have a cylindrical corella as
 well as a lageniform [added: one,] to represent the two stages of floresence
 and the elongated anthers ought not to be represented cordiform


 The three Eriogona are all more or less inaccurate
