And lactic acid, with from five to twenty parts of water; and an
ointment containing a drachm each of bismuth subnitrate and white
precipitate to the ounce. Hydrogen peroxide occasionally acts well.
Trichloracetic acid, usually weakened with one or two parts water, may
be cautiously tried. The application of a strong alcoholic solution of
resorcin, twenty to fifty per cent. strength, is also valuable, as is
also a two to ten per cent. alcoholic solution of salicylic acid.

(Applications are made two or three times daily, and as soon as slight
scaliness or irritation is produced are to be discontinued for one or
two days.)

_Tattoo-marks_ are difficult to remove. Excision is the surest method.
Electrolysis, applying the needle at various points, somewhat close
together, and using a fairly strong current--three to eight
milliamperes--will exceptionally, especially when repeated several
times, produce a reactive inflammation and casting-off of the tissue
containing the pigment; a scar is left.

Several writers claim good results with glycerole of papain, pricking it
in in the same manner as in tattooing.

_Gun-powder marks._ If recent, but a day or so after their occurrence,
the larger specks may be picked or scraped out. Later, electrolysis,
using a fairly strong current, may result in their removal. Their
removal may also be satisfactorily effected with a minute cutaneous
trephine.

#Keratosis Pilaris.#
(_Synonyms:_ Pityriasis Pilaris; Lichen Pilaris.)

#What is meant by keratosis pilaris?#

Keratosis pilaris may be defined as a hypertrophic affection
characterized by the formation of pin-head-sized, conical, epidermic
elevations seated about the apertures of the hair follicles.

#Describe the clinical appearances of keratosis pilaris.#

The lesions are usually limited to the extensor surfaces of the thighs
and arms, especially the former. They appear as pin-head-sized, whitish
or grayish elevations, consisting of accumulations of epithelial matter
about the apertures o
