formation of abscesses in the submaxillary lymphatic glands- 
That this is true in many cases, none will deny ; hut it is no 
less incontestible that simple and accidental inflammations of the 
respiratory mucous membrane may also be accompanied in the 
young and vigorous animal with similar phenomena. This is 
simply due to the facility with which pus is produced in abund¬ 
ance in this species of animals. 
And again, many veterinary writers separate from strangles, 
or at least seem afraid 'to—connect with it the pustular eruption, 
noticed first by Tenner, under the name of grease or sore heels, 
which was overlooked for such a long period, and recognized again 
by Prof. Lafosse, of Toulouse, in 1860, described under the name 
of horse p>ox in 1863, by my eminent master, M. H. Bouley, and 
who made it the essential and fundamental fact, natural and 
specific character. 
For several years, 1 have shown to a class of about one hun¬ 
dred and fifty students that there is no strangles without pustular 
eruptions. It is more or less developed, sometimes difficult to 
see, but is never missing. Every time it is absent it is not stran¬ 
gles which is present, it is a sinple inflammation, not contagious 
by cohabitation, and not inoculable. 
This short introduction is sufficient, I believe, to show how 
vague and uncertain is this question, already so often discussed, 
and to what extent the distinctive points of the disease is ignored 
and poorly described. 
It is with the desire to find my way in this dark road that, by 
attentive observation and experiments of very numerous inocula¬ 
tions, the first amongst which dates back some fifteen years, 1 
have tried to determine the proper name to be given to strangles 
from its nature and analogy to other affections; to tabulate 
what there is really known of its etiology; to distinguish amongst 
its external manifestations those which are proper to it; to isolate 
these from the phenomena, purely contingent, which are some¬ 
times added ; to discover the causes and their nature, and to 
prevent them as much as possible, or, at least, to regulate their 
march.
