ON AN EPIZOOTIC WHICH PREVAILED AMONGST THE 
STALLIONS IN THE IMPERIAL DEPOT OE TARBES. 
By M. Lafosse. 
The nature of epizootic diseases is as yet involved in ob- 
scurity, says the author. The most contradictory opinions 
divide the etiologist on this subject." Some contend that they 
depend on specific causes; others, that they are produced by 
a combination of natural and hygienic effects ; and, finally, 
there are others who profess that the problem of their origin 
is as yet insolvable, and attribute them to that unknown in- 
fluence, to that quid ignotum , called genius epidemic. 
Knowing these differences of opinion, there exists a good 
reason for publishing an account of those facts and opinions 
which bear strong relations on the subject, if it be only to 
furnish elements for discussion. With this view, the author 
has decided to write a work, to which he has given the above 
title, though the epizootic is not of recent date. 
History . — The malady affecting those stallions at Tarbes 
was one of those which show themselves more frequently 
when there is a number of horses congregated together. 
There were many victims to this disease at this depot in 
1822-23, and it is stated in the archives of this stud to be 
gangrenous peripneumonia. There are many proofs that 
this disease prevailed in the cavalry, and among the horses of 
the public conveyances, and recently great losses were sus- 
tained at Begeret and at Visens, in the neighbourhood of 
Tarbes; likewise at Toulouse its ravages were manifested 
among the horses of the 8th Artillery, and in the stable's of 
the postmaster; and at the present time it prevails with 
great intensity in the cavalry quarters of Carcassonne, These 
are facts that ought to throw some light on the causes which 
give rise to this disease. 
Etiology . — This is, according to the author, to be found in 
the atmosphere and certain conditional states of the stables, 
which give activity to the epizootic.
