Although these results are not yet of much impor- 

 tance, a continuance of these theoretically interesting 

 studies is desirable. 



Various bacteria which have in great part been 

 imperfectly studied morphologically and biologically 

 are able to produce butyric acid, butyl alcohol, or 

 both from carbohydrates. 



A review of these varieties is found in an article by 

 Baier (C. f. B., Part II., Vol. I., p. 17). Here we 

 will only mention : bacillus butyricus Hiippe (appar- 

 ently also other allied varieties), the imperfectly 

 described granulobacter poly my xa Beyerinck, and 

 several anaerobic varieties (clostridium butyricum of 

 the authors). 



In connection with the fermentation of sugar we
