CLASSIFICATION OF THE BACTERIA. 57 
punctum, ete., Zooglea, Micrococcus, and many 
others, are vegetable cells, spores of fungi, of sevy- 
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 Schizomycetes, 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 alge 
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. 
Cu. 1. PROTOPHYTES. 
A. Cyanophycee (Oscil- A’. Schizomycetes (Bac- 
latoriacee, etc.). teria). 
B. Palmellacee. B’. Saccharomycetes 
(Ferments).
