Zschokke describes a disease of this kind affecting the ears, back and
croup, and caused by a micrococcus in the epidermis and papillary layer
of the derma. It appears in the form of patches, often of the size of
the palm, showing bluish gray papules which dry up without forming
pustules. It runs a chronic course and produces little or no itching.
_Treatment_ would consist in absolute cleanliness, soapy or alkaline
washes, and the free use of solutions of the hyposulphites, sulphites,
or other antiseptics which are neither irritant nor poisonous.
URTICARIA is met with in swine as already noticed.
SCLERODERMA occurs in boars especially in the region of the shoulders
and back.
