NEW RESEARCHES UPON PLEURO-PNEUMONIA, ETC 
360 
amongst the corpuscles of the air gathered against the plate of 
glass, moist with glycerine, were found globules of pus perfectly 
evident. 
To this fact is added that of Mr. Nepveu, chief of the labora¬ 
tory of the Pitie, recently presented to the Society of Biology: 
A square meter of the wall of a surgical ward, which had not 
been washed for two years, was cleaned, and the liquid squeezed 
out of the sponge used for that purpose, examined immediately 
afterwards. It was blackish in its whole mass, and contained mi¬ 
crococci in large quantity, some microbacteria, and besides epithe¬ 
lial cells in small number, some globules of pus, red globules, and 
finally irregular blackish masses and ovoid bodies of unknown 
nature. The experiment was carried with all precaution to avoid 
causes of error ; the sponge used was new, and thoroughly washed 
in recently distilled water. 
In the stables infected by exudativa pleuro-pneumonia, the air 
condensed upon a vase containing cold water, and collected on a 
clean plate, has given me the proof that this liquid contains the 
peculiar corpuscles that one finds in the lungs of animals affected 
with pleuro-pneumonia. 
A plate of glass moist with glycerine, hung during several 
hours in a stable containing diseased animals, and examined with 
the microscope reveals also the presence of the peculiar corpuscles, 
which I will describe further on. 
That which, experimentally, made me believe also that the ex¬ 
pired air of the lungs of a sick animal, as well as the saliva, con¬ 
tains the germ of the disease, is the fact that diseased animals to 
be given up for consumption, starting from flasselt, before the 
establishment of railways, followed especially three roads—one 
towards the abattoir of Liege, one towards those of Brussels and 
Anvers, the third towards Beverloo. 
And, after some time, all the inns on the road where those 
animals had stopped, and even the farms situated on those roads 
became infected. 
Here amongst others is a fact corroborating the preceding ones : 
A small herd, composed of four or five diseased animals, was 
slowly going towards Beverloo by an out-of-the-way road, when
