trated to an unusual depth by the secreting papillae, and that
at intervals these have bulged out into a vascular fungous mass
comparable to the "grapes."

_Treatment._--In treatment hygienic measures occupy a front rank, but
are in themselves insufficient to establish a cure. All local and
general conditions which favor the production and persistence of the
disease must be guarded against. Above all, cleanliness and purity of
the stable and air must be obtained; also nourishing diet, regular
exercise, and the avoidance of local irritants--septic, muddy, chilling,
etc. At the outset benzoated oxid of zinc ointment may be used with
advantage. A still better dressing is made with 1 ounce vaseline, 2
drams oxid of zinc, and 20 drops iodized phenol. If the surface is much
swollen and tender, a flaxseed poultice may be applied, over the surface
of which has been poured some of the following lotion: Sugar of lead,
one-half ounce; carbolic acid, 1 dram; water, 1 quart. All the
astringents of the pharmacopoeia have been employed with more or less
advantage, and some particular one seems to suit particular cases or
patients. To destroy the grapes, they may be rubbed daily with strong
caustics (copperas, bluestone, lunar caustic), or each may be tied round
its neck with a stout, waxed thread, or, finally and more speedily, they
may be cut off by a black-smith's shovel heated to redness and applied
with its sharp edge toward the neck of the excrescence, over a cold
shovel held between it and the skin to protect the skin from the heat.
The cold shovel must be kept cool by frequent dipping in water. After
the removal of the grapes the astringent dressing must be persistently
applied to the surface. When the frog is affected, it must be pared to
the quick and dressed with dry caustic powders (quicklime, copperas,
bluestone) or carbolic acid and subjected to pressure, the dressing
being renewed every day at least.

ERYSIPELAS.

This is a specific contagious disease, characterized by spreading,
dropsical inflammation of the skin and subcutaneous tissues, attended
with general fever. It differs from most specific diseases in the
absence of a definite period of incubation, a regular course and
duration, and a conferring of immunity on the subject after recovery. On
the contrary, one attack of erysipelas predisposes to another, partly,
doubtless, by the loss of tone and vitality in the affected tissues, but
also, perhaps, because of
