Translation sent to Mr Curtis

Most honored colleague' 



Yesterday I received your letter of the 26th Feb. : unfortunately it had beert sent to 

 N. Braunfels while I stayed in Galveston and my business did not allow me to 

 travel in Texas. The request from Rev. M.A. Curtis appeals to me in that only 

 Cornio^-, Hypho- und Gastero-mycetes are included which cannot be included in 

 my revision of Jones fungorum turquesque rogatorum of which the volume to be 

 published now includes the truffles (Tuberaceae). Before beginning the 

 correspondence I wish to attach a condition: Rev. Curtis can write to me in any 

 European language he prefers; but I will answer in German with English letters 

 and Mr C. if he wants to do good work on mushrooms must learn to read 

 German as must the British, French etc. and I English. He cannot undertake any 

 research without the Jones, which is written in German because it already 

 contains descnptions and analyses ofabout 1000 species. I would be happy to 

 enter into correspondence with him because my time in America is too Short and 

 I have to return this or next week and after our entire task is not scientific but 

 purely mercantile. I had collected quite a bit and will write contributions to Texas 

 fauna, but real research as I am used to have not been done and my collected 

 material is too voluminous to process here without my library. 



In the matter of exchange I am Willing to put aside a few things for him, but 

 I cannot undertake a collection because I have positively no time because I am in 

 Charge of several very rieh
