Dusting-powders of boric acid and zinc oxide, to which may be added from
ten to thirty grains of salicylic acid to the ounce, to be used freely
and often:--

[Rx] Pulv. ac. salicylici ................. gr. x-xxx.
Pulv. ac. borici ..................... [dram]v.
Pulv. zinci oxidi .................... [dram]iij M.

Diachylon ointment, and an ointment containing a drachm of tannin to the
ounce; more especially applicable in hyperidrosis of the feet. The parts
are first thoroughly washed, rubbed dry with towels and dusting-powder,
and the ointment applied on strips of muslin or lint and bound on; the
dressing is renewed twice daily, the parts each time being rubbed dry
with soft towels and dusting-powder, and the treatment continued for ten
days to two weeks, after which the dusting-powder is to be used alone
for several weeks. No water is to be used after the first washing until
the ointment is discontinued. One such course will occasionally suffice,
but not infrequently a repetition is necessary.

Faradization and galvanization are sometimes serviceable. Repeated mild
exposures to the Roentgen rays have a favorable influence in some
instances.

#Sudamen.#
(_Synonym:_ Miliaria crystallina.)

#What is sudamen?#

Sudamen is a non-inflammatory disorder of the sweat-glands,
characterized by pin-point to pin-head-sized, discrete but thickly-set,
superficial, translucent whitish vesicles.

#Describe the clinical characters.#

The lesions develop rapidly and in great numbers, either irregularly or
in crops, and are usually to be seen as discrete, closely-crowded,
whitish, or pearl-colored minute elevations, occurring most abundantly
upon the trunk. In appearance they resemble minute dew-drops. They are
non-inflammatory, without areola, never become purulent, and evince no
tendency to rupture, the fluid disappearing by absorption, and the
epidermal covering by desquamation.

#Give the course and duration of sudamen.#

New crops may appear as the older lesions are disappearing, and the
affection persist for some time, or, on the other hand, the whole
process may come to an end in several days or a week. In short, the
course and duration depend upon the subsidence or persistence of the
cause.

#What is the anatomical seat of sudamen?#

The lesions are formed between the lamellae of the corneous layer,
usually the upper part;
