CLASSIFICATION OF THE BACTERIA. 57 



punctum, etc.. Zooglcea, Micrococcus, and many 

 others, are vegetable cells, spores of fungi, of sev- 

 eral distinct species certainly; spores, or repro- 

 ductive bodies of the first order, derived one from 

 another, either by germination, fission, or from a 

 mycelium ; reproductive bodies, in a word, of the 

 order of those which Tulasne has arranged under 

 the name of conidia, etc." 



Nageli establishes in the inferior fungi which 

 produce decompositions three very natural groups. 



1. The Mucorini, or mould fungi ; 



2. The Saccharomycetes, or budding fungi, which 

 produce the fermentation of wine, beer, etc. ; 



3. The ScJiizomycetes, or fission fungi, which pro- 

 duce putrefactive processes. This last group is formed 

 of our bacteria (Micrococcus, Bacterium), etc. 



Sachs solves the question by uniting the algse 

 and fungi in a single group, the thallophytes, in 

 which he establishes two series exactly parallel, 

 one comprising the forms with chlorophyll ; the 

 other, the forms which are deprived of it, and 

 preserving in a transverse direction the morpho- 

 logical affinities of these organisms. 



As this classification is yet but little known, we 

 think it best to give it in the following table : 



THALLOPHYTES. 



Forms with chlorophyll. Forms without chlorophyll. 



CL. 1. PKOTOPHYTES. 



A. Cyanophyceae (Oscil- A'. Schizomycetes (Bac- 

 latoriacese, etc.). teria). 



B. Palmellacese. B'. Saccharomycetes 



(Ferments).
