EXPERIMENTS ON THE TREATMENT OF GLANDERS. 469 
The external periosteum which covered them was much thick- 
ened, and of a red colour, and could be easily detached from the 
bony tumour beneath. The soft parts which covered them ex- 
hibited no change of structure. The appearance of these tu- 
mours can be produced, in my opinion, by some constitutional 
predisposition alone, as by a lymphatic temperament, or a ten- 
dency to scrophulous affections, as tubercular phthisis, farcy, 
glanders, &c.

NEW EXPERIMENTS ON THE TREATMENT OF 
GLANDERS. 
The cure of glanders is, according to some, ihe despair, and, 
according to others, the disgrace of the veterinary art. It is not 
because experimentalists have been wanting ; it is not because 
their panaceas have failed to accomplish all that they wished, 
for we could give a long list of persons of good credit, and of 
no credit at all, who pretend or believe that they have discovered 
the secret of curing glanders : it is because the confirmation — 
the realization of their announced success has been wanting. It 
is unfortunately found that these remedies lose all their power 
the moment they go from the hands of those who proclaim their 
efficacy ; and the experimentalists themselves lose all their good 
fortune, when they are called upon to treat those patients, the 
real character of whose disease has been ascertained by com- 
petent persons. It is not because veterinarians, in despite of 
their little hope of success, no longer multiply their experiments 
on every occasion, and in every direction : what have they not 
done ? what have they not employed against this fearful disease? 
We will not go so far as to say that a horse affected with 
glanders has never been cured ; for we know some facts that 
have passed under our own eyes, which prove that the horse 
whose fate was despaired of has become apparently well ; but 
we believe that the practitioner has often been deceived with 
regard to the circumstances that have led to a cure. Some horses 
have been cured, that is, they have been said to have been cured — 
the symptoms of glanders have disappeared for awhile : but 
with the disappearance of the symptoms has the disease actually 
been cured ? or has the cure been the result of the means em- 
ployed ? Post hoc , ergo propter hoc. Some have been so for- 
tunate as to obtain almost uniform success in precisely the same 
circumstances in which others have experienced uniform failure ; 
and some have seen the illusion under which they laboured com-
