 My dear Sir,


 Yours of the 8th is just received. I plead
 guilty to apparent negligence in not informing you long since

 description but if not this I give up. There is nothing like it
 in Gray.


 I keep specimens of it and also of Splanchn. angustatum L.
 Most of my leisure time this winter has been spent in reexamining
 my former colllections of the Crypus. I have a few Lichens

 feel interest enough in the matter to reply if I should write
 him? Can you give me his address?


 I am greatly obliged for the use of your Lichens and will
 return them as soon as I can come to Princeton.

 a plant in many respects like Hypnum stillatum, differing
