injurious extent. We have, however, so seldom any satisfaction 
in treating the disease, that it is always our duty, when called to 
a case, to adopt measures for its 
Prevention , which, from what has been said, will be self-evident. 
The succulent herbage in spring and autumn rapidly induces in a 
young animal a state of plethora, the great predisposing cause 
of this disease : an “ excess of healthy stimulus,” as Mr. Youatt 
expresses it, is uniformly associated with its appearance. Short 
pasturage, where the animals will have to wander over a greater 
extent for less food, are, then, plainly indicated to counteract this, 
and experience has shewn it does so effectually. Rowels and 
setons are by some employed. Their utility, to any great extent, is 
questionable. The system, after a time, becomes so inured to them, 
that their action is almost imperceptible. Purgative medicine and 
bleeding, it is easy to see, may for the time being ward off the 
disease; but it is very apt to recur after the change they have in- 
duced has passed by. Nothing, in fact, can be depended upon but 
keeping the animals from too luxuriant feeding. Specific medicines 
do not deserve notice. The disease requires for its development a 
gradual operation of certain causes, in the avoidance of which im- 
munity from its attack alone exists. 
There are certain microscopical appearances presented in this 
disease different from those denoting ordinary inflammation, and 
confirmatory of the view I have taken of its pathology ; these, 
however, I should wish to extend, when, at a future period, I hope 
to draw your attention to some further remarks respecting the mi- 
croscopical appearances of this disease, and of some other affec- 
tions, as glanders and farcy, particularly as to the nature of the 
discharges attending the latter, a point of no less interest than im- 
portance to the scientific practitioner.

ON THE COMMUNICABILITY OF GLANDERS FROM 
THE HORSE TO THE HUMAN BEING. 
Notwithstanding the numerous instances of the facility with 
which glanders is communicated from the horse to the human 
being that have occurred during the last few years, it appears 
to us that a belief in the transmissibility of this frightful disease
