form.

_The treatment_ consists in changing the ration and keeping the animals out
of the sun, or long grass and weeds for a few days. This is all the
treatment required in most cases. It may be advisable to administer a
physic. If pus and scabs form, the part should be cleansed daily with a one
per cent water solution of permanganate of potassium.

HERPES (FUNGOUS SKIN DISEASE).--This is a contagious disease of the skin
caused by thread fungi, _Tricophyton tonsurans_ and _epilans_, which
develop in the skin in localized areas, causing vesicles, scabs or scales
to appear, and the loss of the hair over the part. This skin disease occurs
in all domestic animals, but it is most commonly met with in cattle. It
usually affects young cattle. It most commonly occurs in the region of the
face and neck. Thick, bran-like crusts form over the scattered areas of the
skin and the hair drops out or breaks off. The animals frequently rub the
infected area.

_Prompt treatment_ may prevent the spread of this disease in the herd. It
may be checked by quarantining the infected animals and scrubbing the
stalls, stanchions and walls with a disinfecting solution. Grooming the
infected animal should be discontinued. This skin disease responds most
readily to ointments. Flowers of sulfur one part and lard ten parts is
commonly used by stockmen. Sulfur-iodide ointment, or tincture of iodine
may be applied.
