236 VETERINARY SURGICAL THERAPEUTICS. 
various cutaneous localizations of horse-pox. The various forms of this af- 
fection have been known since the observations of Lafosseand Bouley. At 
times the eruption is generalized, and pustules in varying numbers exist on 
the skin, which are isolated in some regions, agglomerated in others, and 
sometimes localized in one region, or again in several. Frequently it oc- 
curs on the inferior parts of the legs, giving rise to that form of phlegmasia 
which, towards the end of the last and beginning of the present century, 
English farriers called grease, and which Jenner has named “ shore-heels.” 
Extending over large surfaces, it resembles acute grease (eaux-auxjambes 
aigues) ; sometimes it is added to some recent or old lesion, to a wound 
of operation, to necrosis of the scutiform cartilage or of the tendons, and 
may be supposed to be an erysipelatous outbreak ; again, in other cases 
it is confluent on the inferior parts of the head, on the skin of the lips, 
of nostrils, on the pituitary membrane, and is accompanied with lym- 
phangitis or adenitis, and these present a clinical aspect which at first 
may make one believe it farcy or glanders; it is also that which, when 
located upon the buccal mucous membrane, constitutes the disease de- 
scribed under the name of contagious pustular stomatitis. 
Lafosse and Bouley have shown, by inoculation of cattle, the true nature 
of this eruptive affection with so many manifestations: the fluid of the 
pustules, inserted in the skin of heifers, has produced vaccine. 
The cutaneous phlegmasias produced by horse pox may affect lymphatics 
in various degrees, but their typical progress, their peculiar characteristics 
and their short duration render the diagnosis easy. Even on the fetlock 
or the coronet it is easy to differentiate the eruption of horse-pox from 
gangrenous dermatitis (cutaneous quittor) from scratches or from “ grease.” 
Since the disease is very contagious, prophylactic measures are im- 
portant. Avoid the transportation of the virulent serosity by means of 
instruments used for cleaning the animals. The cyclic evolution of the 
eruption, and in the generality of cases its benignity, disprove active 
interference. Ordinarily it is sufficient to watch the progress of the disease 
and attend to the complications that may appear, such as lymphangitis, 
adenitis, etc. The application of absorbing or antiseptic powders at the 
stage of exudation and in the cases of acute inflammation of the skin of 
the lower parts of the extremities, rest, carbolic or cresyl warm baths 
and wadded dressing constitute all required therapeutics. 
Moller advises dusting the diseased parts with a mixture of tannin 
and iodoform, or covering them with an ointment of paraffin and red 
oxide of mercury with a wadded dressing, which is left fora variable length 
of time, according to the amount of suppuration.
