it is on account of thickness in the liquid and that the vibrio of 
the deep layers is protected by the organisms of the superficial 
layers. 
5. The septic vibrio lives and multiplies in the perfect vacuum, 
as in the purest carbonic acid gas. In these conditions, it is 
entirely modified. It loses its filiform aspect, resorbs itself, and 
leaves in its place corpuscles, which soon germinate. 
6. The germs of the septic vibrio may form a dust that can 
be carried of by the wind, and that water may hold in suspen¬ 
sions. 
7. Even in compressed oxygen, (several atmospheric pressures), 
these germs will conserve their vitality and their power of repro¬ 
duction. 
8. These germs are fecunds in the perfect vacuum, and pure 
carbonic acid gas, if they meet with a nutritive matter, proper to 
their development. 
9. Among the microscopical ferments of diseases, and amongst 
the organisms, whose presence excite or complicate morbid mani¬ 
festations, are, 1. Beings which are exclusively aerobics ; 2. Beings 
which are both aerobics and anerobics; 3. Beings which are exclu¬ 
sively anerobics. 
10. The denominations and classification of vibrios proposed in 
later years cannot be established, as first thought, from morpho¬ 
logical considerations. The septic vibrio, for instance, passes, 
according to the parts where it is cultivated, through forms, length, 
and sizes s© different that one would think them to be specific 
individuals—separated and distinct forms from each others.—

MANNER OF COLLECTING THE VIRUS OF PLEURO-PNEUMONIA, AND 
MODE OF INOCULATION. 
The inoculation of pleuro-pneumonia, says Mr. Robouane, is an 
excellent measure, providing the virus is well obtained, and its 
effects can be watched, especially in summer. He proceeds as 
follows; 
An animal being destroyed during the period of acme, the
