'\\^hile at present these results are not of much value, 

 yet a continuance of these theoretically interesting studies 

 is desirable. (Comi3are special part, under Vibrio cholerae 

 and Bact. coli. ) 



Various bacteria — often, however, insufficiently studied 

 morphologically or biologically — are able to produce buty= 

 rlc acid, butyl alcohol, or both from carbohydrates. 



For a review of these varieties see Baier ( 0. B. L. i, 

 17). Compare in special part : Bac. butyricus Hiippe, 

 Bac. butyricus Botkin, Clostridium butyricum, etc. 



In connection with the fermentation of sugar, de= 

 composition of cellulose may be mentioned as caused by 

 various bacteria. It occurs especially in the gastric and 

 intestinal contents of herbivora, and also in 

 and forms marsh-gas as its striking product. 



1 The statements regarding the coli group are from Nencki (C. B. 

 IX, 305) ; regarding the typhoid, from Blachstein ; regarding the 

 cholera group, from Kuprianow (A. H. xix, 283, 291) and Gosio (A. 

 H. XXI, 114). ^
