strength, is also useful. An excellent application
for beginning areas on the scalp is a solution of the red iodide of
mercury in iodine tincture, one to three grains to an ounce.

A compound ointment, containing several of the active remedies named, is
convenient for dispensary practice, such as:--

[Rx] [beta]-naphthol, ................. [dram]ss-[dram]j
Ol. cadini, ......................... [dram]j
Ungt. sulphuris, ............ q.s. ad [Oz]j. M.

In that form known as tinea kerion mild applications are demanded at
first; later the same treatment as in the ordinary type.

#How is ringworm of the bearded region to be treated?#

On the same general plan and with the same remedies (excepting
chrysarobin) as in ringworm of the scalp. Depilation is to be practised
as an essential part of the treatment. Special mention may be made of an
ointment of oleate of mercury, sulphur ointment, a lotion of sodium
hyposulphite ([dram]j-[Oz]j), and a lotion of corrosive sublimate (gr.
j-iv to [Oz]j). The _x_-ray has been used in ringworm of this region
with alleged success, pushing it to the production of a mild erythema
and depilation. The above methods are, however, usually successful, and
are without risk of damage.

#How is the certainty of an apparent cure in ringworm of the scalp or
bearded region to be determined?#

By the continued absence of roughness and of broken hairs and stumps,
and by microscopical examination of the new-growing hairs from time to
time for several weeks after discontinuance of treatment.

Cure of ringworm of the general surface is usually self-evident.

#Is systemic treatment of aid in the cure of ringworm?#

It is doubtful, although in children in a depraved state of health the
disease is often noted to be especially stubborn, and in such cod-liver
oil and similar remedies may at times prove of benefit.

#Tinea Imbricata.#
(_Synonym:_ Tokelau Ringworm.)

#What is tinea imbricata?#

A vegetable parasitic disease of moist tropical countries, characterized
by the formation of patches composed of concentrically arranged,
imbricated, scaly rings. It may begin at one or several points as a
brownish, slightly raised spot, spreading peripherally; the renewed
epidermis of the central part of the patch goes again through the same
process; the result is a small or large area of concentrically arranged,
imbricated,
