* This Table makes no attempt whatever at completeness. In particular, the list of 

 oxidative dissimilation processes with organic substrates can be expanded indef- 

 initely. As for the fermentative dissimilation processes, the most important types 

 known today are represented, with the exception of the anaerobic decomposition of 

 protein breakdown products. These have been omitted because it is very difficult 

 to denote them by means of simple equations. See, however, Arch. f. Hyg., 66, 

 209, 1908.
