path we have yet to travel. Let us look around us a little, and 
somewhat retrace our steps. Glanders is inflammation of the 
Schneiderian membrane, strictly local for awhile, and often for 
a long while, and during its insidious state; and even when the 
discharge becomes gluey, and sometimes after chancres have 
appeared, the horse is apparently well. There are hundreds of 
glandered teams about the country with not a sick horse among 
them. Do not listen to the accounts which you hear of the 
glandered horse being necessarily more or less out of condition, 
or that some deviation from health is necessary to his receiving 
the infection of glanders. Do not puzzle yourselves with the 
distinction between “ healthy and unhealthy disease,” a strange 
connexion of terms, and as unintelligible as many parts of an 
otherwise valuable work on glanders. Quit the dangerous yet 
often fascinating regions of theory, and look beyond the walls of 
an infirmary, where disease alone is found and lives. Go into 
practice, examine the stables of the farmer and the post-master 
and the waggon proprietor, and more particularly the miserable 
huts that shelter the barge-horse. These are the very domain of 
glanders, and many an inhabitant yields to its influence. When 
the disease has developed itself in all its chancrous malignancy 
and power, we see enough, and more than enough, of its ra¬ 
vages ; but, ere it throws off the mask, although it is in full 
possession of its victim, where do we find horses so hardy, so 
healthy, so capable not only of ordinary but of cruel exertion ? 
I cannot say that glanders, like the rot, improves the condition, 
but I am sure that often, and for a long while,—for months and 
even for years,—it does no injury to the general health. The 
inflammation is purely local, and is only recognized by that in¬ 
variable accompaniment of inflammation,—increased secretion. 
Although that secretion is poisonous, and its neighbours fall 
victims to it, it affects not the animal whence it came. But 
this continued inflammation at length tells, or other circum¬ 
stances increase its power and its effect, and the vitality of the 
tissue is destroyed, and suppuration succeeds ; but not that of 
a healthy character—not that which is connected with reproduc¬ 
tion,—it is malignant and destructive from the beginning; and 
soon another process commences, salutary or destructive, ac¬ 
cording to circumstances. There are absorbents on every sur¬ 
face; they are found on the surface of the chancres which are 
beginning to appear; and they take up the fluid which is secreted 
from the ulcers, and they soon feel its poisonous influence. The 
absorbents become inflamed and tumid, and, where the virus 
rests, as it were, namely, at the valves, destruction of the part 
ensues, and the chancres spread in every direction.
