terized by caseating nodular
swellings, first of the skin and afterwards of the superficial lymphatic
vessels and glands, finally proving fatal within a year by extension to the
viscera. The swellings rupture and discharge a purulent yellowish fluid,
which contains the causative organism. This affection, called farcin du
boeuf by the French, resembles cutaneous glanders or farcy of horses, but
is caused by an entirely different organism, the streptothrix of Nocard.
Moreover, cattle are immune from glanders, and for this reason the name,
unfortunately applied to this disease, should not lead to any confusion
with the cutaneous glanders or farcy of horses. Although the disease has
been described as occurring only in Guadeloupe and France, the possibility
of its occurrence in American possessions warrants its mention in this
chapter.

_Treatment._--Treatment consists in making incisions into the swellings and
syringing them out with 2 per cent compound cresol solution. The cavities
may then be packed with cotton, soaked in 5 per cent zinc-chlorid solution.
The swollen lymphatics may also be bathed or covered with cloths wrung out
in this solution.

of the large body cavities. In the thorax the serous membrane (pleura)
covers the ribs and diaphragm as well as the whole lung surface. In the
abdomen a similar membrane (peritoneum) lines the interior of the cavity
and covers the bowels, liver, spleen, etc.
