          a week with cough and general indisposition, and a week more
 elapsed before I could [added: take] exercise on horseback. Gray has not
 gainsaid my averment that it is a new species, or you would
 have had the kindness to let me know the fact. If you do not
 approve of R. [Rhus] exaltata as a name, what do you say to R. nigrimontana
 R. incognita, R. praetermissa, R. pinetorum or rather abietinorum

 I am sorry Gray has not a copy of his Mountain Travel

 the present one is four years old, or had I better take [added: or order] the existing
 edition?

 I believe it is now cultivated in France? 
 [added:?]


 The last number of the Prodromus I have is tom XIII [?]
 sectio II; is sectio prior yet published, or any volume subsequent?
 Gray says that they were nearly ready when he wrote. He does not say
 whether any one is going to continue Kunth's Enumeratio; perhaps
