          Zoology keeps him busy.


 Dr. Gray sent me his monograph
 on the Erigoneae. Our 
 friend Bloomer has no copy;
 if you can spare one, please
 send it to him. He is an incessant 
 laborer in  botany.


 I await with a great deal
 of anxiety the monograph
 of the Polemoniaceae. This will
 assist us materially, since we have
 so many of them still to be determined.


 I will see what I have of the
 Hydro phyllaceous order. We
 have at least some very nice specimens
 of these previously sent to Dr.
 Gray. They may be of some value
 to you.


 We will send to Dr. Engelmann
 what we have of the Quercus.


 Please call Baker attention
