HERPES.

This name has been applied to a disease in which there is an eruption of
minute vesicles in circular groups or clusters, with little tendency to
burst, but rather to dry up into fine scabs. If the vesicles break, they
exude a slight, gummy discharge which concretes into a small, hard scab.
It is apparently noncontagious and not appreciably connected with any
disorder of internal organs. It sometimes accompanies or follows
specific fevers, and is, on the whole, most frequent at the seasons of
changing the coat--spring and autumn. It is seen on the lips and
pastern, but may appear on any part of the body. The duration of the
eruption is two weeks or even more, the tendency being to spontaneous
recovery. The affected part is very irritable, causing a sensitiveness
and a disposition to rub out of proportion to the extent of the
eruption.

_Treatment._--It may be treated by oxid of zinc ointment, and to relieve
the irritation a solution of opium or belladonna in water, or of sugar
of lead or oil of peppermint. A course of bitters (one-half an ounce of
Peruvian bark daily for a week) may be serviceable in bracing the system
and producing an indisposition to the eruption.

BLEEDING SKIN ERUPTIONS, OR DERMATORRHAGIA PARASITICA.

In China, Hungary, Spain, and other countries horses frequently suffer
from the presence of a threadworm (_Filaria haemorrhagica_ Railliet, _F.
multipapillosa_ Condamine and Drouilly) in the subcutaneous connective
tissue, causing effusions of blood under the scurf skin and
incrustations of dried blood on the surface. The eruptions, which appear
mainly on the sides of the trunk, but may cover any part of the body,
are rounded elevations about the size of a small pea, containing blood
which bursts through the scurf skin and concretes like a reddish scab
around the erect, rigid hairs. These swellings appear in groups, which
remain out for several days, gradually diminishing in size; new groups
appear after an interval of three or four weeks, the manifestation being
confined to three or four months of spring and disappearing in winter. A
horse will suffer for several years in succession and then permanently
recover. A fatal issue is not unknown. To find the worm the hair is
shaved from the part where the elevations are felt, and as soon as a
bleeding point is shown the superficial layer is laid open with the
knife, when the parasite will be seen drawing itself back into
