398 EXPERIMENTS ON THE CONTAGION OF GLANDERS. 
duced under the sub-cutaneous cellular tissue of the neck. Six 
days afterwards two little glands, slightly sensitive and slightly 
adherent, were produced, but they soon disappeared, and did not 
return. 
Experiment VII.—Injection into the jugular of matter taken 
in the second stage of the disease. Three days after the injec¬ 
tion a large swelling, of a gangrenous nature, developed itself 
in the upper part of the bosom; it rapidly extended up the neck, 
accompanied by evident symptoms of adynamia, and destroyed 
the horse sixty hours after its first appearance. Examination, 
twelve hours after death, shewed all the characteristics of gan¬ 
grene and alteration of the blood. It acted in the same manner 
as other fluids in a state of putrefaction. 
Experiment VIII.—Two sound horses, Nos. 413 and 730, 
were placed between two horses glandered in the second degree, 
and with abundant sanious discharge. They all fed together, 
they were taken care of by the same men, and dressed with the 
same instruments. They remained together from the 15th of 
November to the 1st of January without any result. Two months 
after this they were in perfect health. 
We should have instituted many other experiments tending 
to the same point, but we received orders to discontinue our 
labours. 
Setting out of the question some appearances in the horses 
inoculated in the pituitary membrane, and which at first made us 
fear that contagion had taken place, all these experiments have 
had only a negative result; and the conclusions against the con¬ 
tagiousness of glanders acquire additional probability, when it is 
recollected that the animals on which we experimented, were 
those that seemed to be in a situation most favourable for being 
affected by this disease; for they had had farcy, and they had 
been debilitated by the regimen to which they had been sub¬ 
mitted at Betz, and which was every thing but of a tonic nature. 
We should, perhaps, add another fact, not less conclusive. 
The infirmary at Betz generally contains about 400 horses labour¬ 
ing under different stages of glanders. The infirmary is but a 
little way removed from several small farms, and it is close to 
one of them. Our horses are continually in contact with those 
of the neighbouring farmers. In the two years that this in¬ 
firmary has existed there has not been a case of glanders within 
a league of it: would this have happened if the disease had 
been contagious ? 
We presume not to force upon others the opinion at which we 
have arrived. The contagious nature of glanders is too deeply
