CAUSE OF GLANDERS. 197 
a very guarded prognosis when a fracture of these bones, or any 
injury to the nasal cavity, occurs. 
Every previous Disease .—It is easy to conceive why various 
affections of the respiratory passages, I must not say run on to 
glanders, but predispose the Schneiderian membrane to take on 
the peculiar inflammation of glanders; and that it should be the 
sequela of strangles, and catarrh, and bronchitis, and pneumonia. 
There is continuity of membrane, and association of function, 
and a thousand sympathies. Of catarrh, however, I would say 
that we probably may be liable to considerable error. That 
which we consider to be catarrh may, in fact, be glanders under 
its insidious form ; appearing, intermitting, returning, now under 
a more threatening, and then scarcely recognisable, form, until 
at length it assumes its true and undeniable character; the 
glands also enlarging, and diminishing, and almost disappearing, 
and then as prominent and hard as before, playing about the 
inner surface of the lower jaw-bone, as if desirous yet fearful of 
adhering to it. All this I can easily comprehend, but I must 
have it beaten into me by experience,—and experience does prove 
it to me,—that pleurisy, and hepatitis, and fistulous withers, and 
mange, and inflammation of the testicle, and fracture of the sa¬ 
crum (I am narrating from my own experience), and epidemic 
catarrh (and that within a few days of the present time), and 
quittor, and founder, and grease, shall terminate in glanders. 
My revered friend, Mr. John Percivall, castrated a three-year-old 
colt: the wound did not take on a healthy character, and on the 
seventh day pimples began to appear in a connected chain, run¬ 
ning from behind the stifle towards the posterior extremity of the 
buttock. The next day they assumed the form of buds, and 
there was between them the connecting corded absorbent. On 
the tenth day similar swellings appeared on the other thigh. Oil 
the following day considerable discharge appeared from the 
nose; the chancres of glanders were evidently to be seen, and 
the colt was destroyed on the twenty-sixth day, decidedly far¬ 
cied and glandered. How is all this? Is this the natural ter¬ 
mination of almost every disease of the horse ? No: for, as I 
have already observed, there are many countries where glanders 
is unknown. It is the consequence of our preposterous treat¬ 
ment of the horse—of that injurious stimulus, and consequent 
debility, and predisposition to take on any and every morbid 
action to which we have exposed this vascular and sensitive 
membrane. I am happy here to be able to agree with Mr. 
Vines;—there is not a disease which may not lay the foundation 
for glanders:—I must not say, which may become the cause of 
glanders, but which may dispose this delicate, abused mem-
