Braun 1 is working lately on I soetes , Selaginella , and at times 

 still on Ohara e ; But I do not know, if in the near future a conclu - 

 sion can be expected ; I fear , that always a new delay is to be ex- 

 pected.» , 



I myself sit behind the Hym eno ph yl 1 a e , who'se structure and 

 Gemination has not been eocplored enough by a long way, and have wor- 

 ked up the systematical part as far as raaterial was present f , but am 

 awaitin^: for a conclusion of the latter still sev original speci- 

 mens, and for this reason the printing of the study has been post - 

 poned • Otherwise I enclose a dissertation about various fern Stents-,, 

 which appeared a few months back, My activities with the material of 

 the Leytner Museum, which, und er the direction of Miquel becane avai- 

 lable, in fact were presented to me in the raost liberal way,I^unfor - 

 tunately, can not send, becau.se I did not receive a copy. Düring the 

 course of this Summer I will have the Chance to examine all original 

 specimens of Bleime 1 s work on fernst The mass deposited in the Leyd- 

 ner Museum exceeds all expectations. 



If you have occasion some time to raake a shlpment here, an en- 

 do sure of Cherletter* s Genoles (?? E. D. ) would be raost desi^ed. 



Unfor tunately, your letter arrived only in the mornlng of the 

 last day of the Blenn auction, and, thus, only the last of your de - 

 siderata could be obtained, which you will Sae enumerated on the en - 

 closed. sheet; the biggest part of the books were paid for very dearly, 

 Some of your des^derata are very rarely f ound at all, e.g. Hooker 

 and Gurille, icones filicum; for a 2/3 complete specimen, i.e. the 160 

 first tables with their corresponding text ( the e^tire book contains 

 240 tables) a rrice of ?M Thaler was bid then«. 



I wrote to Schmidt in Halle right a way, but received all de- 

 sired books only after repeated" inquiries-, and unfor tunately , there 

 is a problem, which delays the shipraenf, naraely the work by Krombholz
