may disappear for a time, only
to return again with renewed vigor. It is not regarded as contagious.

TREATMENT. Thorough and protracted constitutional treatment is required
to overcome this disease. Dr. Pierce's Golden Medical Discovery should
be taken internally and also applied locally to the affected parts. To
every other bottle of the "Discovery" which is taken, one-half ounce of
the iodide of potash may be added. One or two of the "Pellets" taken
daily will prove a useful adjunct to the "Discovery."

Locally, we have sometimes applied a lotion made of oxide of zinc,
one-half drachm; benzoic acid, two drachms; morphine, five grains;
glycerine, two ounces. Tincture of the chloride of iron, one drachm in
one ounce of glycerine, makes an excellent local application. Whatever
the local treatment may be, however, we chiefly rely upon the
_persistent_ use of the best alteratives, or blood-cleansing medicines.

AFFECTIONS OF THE HAIR-FOLLICLES.

FAVUS (_Scald Head_) is a disease peculiar to the hair-follicles, and is
indicated by the formation of small yellow crusts, having the form of an
inverted cup. The eruption has a very offensive odor. When it appears in
isolated cups, it is termed _favus dispersus_, but it often occurs in
large clusters, as represented in Colored Plate II, Fig. 12, and is then
termed _favus confertus_. It generally affects the scalp, but sometimes
extends to the face and neck.

CAUSE. Favus is caused by nutritive debility, which results in a
perverted cell-growth.

SYCOSIS (_Barber's Itch_) is an inflammatory affection of the hair
follicles of the face. The prominent features of the disease are redness
and the formation of scales. It is peculiar to males. It has received
various names, according to its predominating characteristics, such as
_sycosis papulosa, tuberculosa_, and _fungulosa_. Colored Plate II, Fig.
10, is a line illustration of sycosis as it appears on the cheek.

CAUSES. Various causes induce the appearance of sycosis. The general
causes are nutritive debility, vicissitudes of heat and cold, and an
exhausted state of the nervous system. It may also result from various
chronic diseases, such as syphilis and dyspepsia.

COMEDONES, or _grubs_, are due to a retention of the sebaceous matter in
the follicles. The sebaceous substance undergoes a change, becoming
granular and somewhat hardened. It gradually extends to the mouth of the
follicle, where it comes in contact with the
