My dear l-tL'. Daven]3ort-i 



I 3onO vitli this a sample of Khat I take for the true dlssectun 

 of vhlcli I send a transcript of Sprengii's original which I have re- 

 cently found. It is no more liKe the dissectim that I have been disre- 

 garding even as a variety than B. simplex Is like B. raatricariae- 

 foldiuTTi or ajiy other closely related species. It is as distinct fl?om 



B.oblinvium as aiiy two or o\xr related species of Hcy no Aspldiiim for 



I s'v- in order for v/ork to live one must TOite it that rray. How really 

 don't you agree \7ith me in this? The Indiana speciBien I send because 

 all my other material is mounted, I now have it from Ky, Ind. Md. and 

 Nev York. Sprengel's type cam e from a Southern locality (Virginia). 



I T'ovJcI like the specimen back poor as it is just for the locality. 

 And I T/otild like the description back. 



Nov-, my friend I want to ask a favor. I have to give a lecture on 

 The Haunts and Habits of ferns and would like like to knovf if you Jjave 

 in stock any lantern slides illustrating the f -rst part of the subject. 

 If so vrould yo\i be vriiiing to loan me a half dozen or so that would 

 serve to shovr them up in their native conditions. This matter &as 

 come upon me suddenly and vrhile I have quite a large stock of mate- 

 rial , T have little that vrould be of value for just what I want. 

 Yours in haste-.
