Sometimes there will appear on the penis of the Stallion, small white
blotches, on the surface of the skin, from the size of a pin’s head to
that of a grain of wheat, which, on the following day will be double
in size. On the third or fourth day, a pea might be set in the ulcers,
which will emit an offensive odor, and which will spread with great
rapidity.
In the mare blotches will appear on the shape, of a deep red color,
apparently eaten through the surface of the skin, which will enlarge
very rapidly. In a day or two, small tumors will appear, extending from
the shape in a downward direction to the hams. These tumors are of
different sizes, varying from that of a pea to that of a half gallon
crock. They are of a very virulent nature, very often causing a painful
rawness in the entrance to the womb, and extending from one to one and
a half inches.
