A. LIAUTARD. 
A trichinia, removed from its envelop, was placed under the micro¬ 
scope, in a weak solution of common salt, leaving it all its liberty of 
motion. At the surrounding temperature (23 degrees C), motions were 
limited ; at a heat of 35 degrees to 45 degrees C. they increased vio¬ 
lently, to stop entirely at 46 degrees. The heat was raised one degree 
more, and then gradually lowered to 35 degrees, and weak motions 
returned from 42 degrees. By a new increase of heat from 35 degrees 
to 40 degrees motions of elongation and contraction of the whole body 
were soon visible, but less marked than in the first experiment. They 
diminished at 42 degrees, and then ceased completely at 44 degrees. 
In another experiment the author did not observed the death of 
the free trichiniae only at 48 degrees C. 
Observing afterwards upon an encysted trichinia, the motions ceased 
at 44 degrees, and reappeared but weakly at 30 degrees. The cyst 
being torn and the trichinia free, the motions showed themselves again, 
disappeared at 45 degrees. 
In another experiment they stopped at 44 degrees. In conclusion 
the author says that a heat of 48 to 50 degrees will kill the muscular 
trichinia. (Archives Veterinaires .) 
CONTRIBUTION TO THE STUDY OF THE EXPERIMENTAL AND 
COMPARATIVE PATHOLOGY OF GLANDERS. 
The author observes that the spontaneous production of the virus 
of glanders is yet to be proven. The transmission of the disease takes 
place by contagion ; but it is not necessary, according to him, that the 
virus deposited upon the skin or the mucous membrane, produce on it 
a local lesion, starting point of a generalization. Most of the time the 
disease is due to an infectious miasma in suspension in the air which, 
penetrating into the lungs, determine a primitive poisoning of the blood 
with specific secondary products, or a primitive localization in the lungs 
followed by a general infection. Autopsies of horses prove this : in 
some ulcerations of the nasal fossoe and cutaneous lesions are missing, 
while in others lesions are found in the larynx and in the lungs. Con¬ 
sequently this virus is at the same time fixed and volatile. It is not 
true that it always affects the nasal mucous; out of 52 post-mortems of 
glanders and farcy, 5 times the nose was found free from lesions. Still 
this is the seat of predilection for these lesions, whatever may have been 
the mode of infection of the animal.
