CONTAGIOUS CHARACTER OF STRANGLES. 583 
Paulet affirms that strangles may be communicated, like the 
scab, either by inoculation or by deglutition*. 
Brugnone declares strangles to be contagious ; and says that 
if it appears in a troop of young horses, the others will speedily 
have it, unless the diseased horse is separated in timet* 
Bose, in “ Le Cours Complet d’Agriculture,” says, “ Every 
stable in which there has been a horse with strangles should be 
thoroughly cleaned ; its racks and mangers well washed, and 
its walls lime-whitened.” 
Sacco says that strangles is eminently contagious}. This in- 
genious physician inoculated twenty-three colts with the vaccine 
matter, and only one of them had strangles afterwards. 
De la Gueriniere , LaJ’osse , Dutz , Vitet , and Lornpagreu 
Lapole say nothing of its contagious character||.

|| Among the modern French writers, Patel gives no opinion about the 
matter; Rodet gives no decisive one, hut acknowledges that he always 
separates the horse with strangles from his companions, as a measure of pre- 
caution. Gasparin maintains the contagiousness of strangles; but Hurtrel 
d’Arboval, and he is great authority, after a lengthened discussion of the 
subject, and of the very experiments which are related in this paper, says, 
that “ he may be permitted to doubt the contagious character of the affec- 
tion called strangles.” There is, however, another foreign writer from 
whose experiments, so far as inoculation with the matter of strangles is 
concerned, there lies no appeal ; I refer to M. Toggia, of Turin. He inocu- 
lated no fewer than eighty colts; some with the matter discharged from the 
nose before the abscess had broken, and others with the purulent matter ob- 
tained from the abscess; and in all of them he observed cough, a small dis- 
charge of mucous matter from the nostril, inflammation of the glands of 
the neck, and the formation of an abscess which either broke of itself or 
which he. opened. The disease assumed the mildest form, and in none of 
the colts did it appear a second time*. 
This is coming to the point ; and if the disease can be propagated by the 
matter from the nose, or from the tumour being brought into contact with 
an abraded or wounded surface, it is as much contagious as syphilis or rabies ; 
and due precaution should be taken in removing young horses at least out 
of the reach of danger. 
The opinions of English writers are as contradictory as the assertions of 
our continental brethren. Peall and White, indeed, hazard no opinion on 
the subject. Mr. Coleman, as appears from my MS., but I believe verbatim 
records of the Professor’s lectures in the years 1813 and 1814, used the 
following language : “Strangles is certainly a contagious disease; it has 
been produced by inoculation, yet but few become affected in this way ; and 
when many young horses become affected at the same time, it is because 
they have been all exposed to other causes far more prevalent than 
strangles.”
