follicles are inflamed and sometimes infected with pus germs. This results
in skin eruptions varying in size from the point of a pin to about a
quarter of an inch in diameter. This inflammation is most prominent during
the warm weather.

_The causes_ are local irritation to the skin from lying on filthy floors,
sweating and irritation from the harness. According to some writers, pus
germs are the only cause, the mechanical agents merely aiding in the
production of the infection.

The face, side of the neck, shoulders, back and sides of the trunk and
quarters are the usual seats of disease. The pimples or nodules may
disappear within a few weeks, or persist throughout the warm season. The
eruption may disappear without leaving scars, or suppuration occurs and
small bald spots result.

_The treatment_ consists in removing the cause of the disease and cleaning
the skin with antiseptic washes. The surroundings of the animal must be
kept clean and a good bed provided. If possible, the horse should be laid
off from work as soon as the condition is noted. Washing the part with a
weak water solution of permanganate of potassium may be practised daily.
Fowler's solution of arsenic may be given. This may be given with the feed.

ECZEMA.--This is an inflammation of the vascular capillary bodies and the
superficial layer of the skin. There may be marked inflammatory exudate,
causing the surface of the skin to become excessively moist and more or
less itching. Redness, vesicles and pustules may characterize the
inflammation. In the chronic form the skin may become thickened and greatly
changed in structure.
