healthy subject; and again, even if it was gourme, similar acci¬ 
dents may follow the experiment, which would leave the observer 
in the same hesitation. For these reasons equine subjects cannot 
be used for this experiment. 
Upon a bovine subject it presents the double advantage of being 
harmless, and to be so positively demonstrative that no doubt can 
remain. 
Bovines not being apt to become glandered—at least by the 
simple insertion of virus made with the lancet, if the liquid which 
is inoculated is of glanderous nature, the result will certainly be 
negative. With the variolic liquid, on the contrary, taken upon 
a recent eruption, vaccinal pustules will always be developed, 
providing the animal has been virgin of the disease, and those 
pustules cannot be to-day confounded with any other cutaneous 
disease. If, then, a positive result is obtained, no matter how bad 
the sore may have looked, or how bad the character of the sup¬ 
puration, one will have the complete proof that the affection is 
simple, and will get well by the efforts of nature alone. 
The inoculation of a bovine is an easy means here, economical 
and harmless for the subject of experiment, consequently essen¬ 
tially practical to decide with certainty the differential diagnosis 
between horse-pox and glanders. I believe, that in this point of 
view, it is called to render assistance in some cases. 
And now, how do the complications above described take 
place ? The fundamental condition of their production is evi¬ 
dently the pyrogenic aptitude so fully developed in the equine 
organism. Under this condition he holds the first rank. All his 
tissues become irritated and suppurate with such facility that the 
simple puncture of a lancet scarcely closes up by first intention. 
Still the physiological quality is not equally marked in all sub¬ 
jects. There are notable differences between the animals of high 
breed, with fine and elegant construction, whose temperament is 
nervous or sanguine ; and those with heavy and thick form,whose 
disposition is lymphatic. In these last the formation of pus 
is in all similar circumstances much more abundant and developed 
than in the others. And then we see in them the suppurative 
lymphangitis of gourme, which is more common and more
