This sort is very common and very annoying to females, from the
age of fourteen and upwards, as they give the skin a dirty greasy
appearance, which no washing will remove. The vulgar opinion that
such pimples are caused by worms or grubs, is quite erroneous. The
best means of removing the worm pimple, is by squeezing out all the
thickened matter of each; for, unless you do this, it is impossible
to get rid of them, as no wash nor other application will remove
them, nor will they ever disappear of their own accord. Several
things may be useful in preventing their return. Of these, the Roman
balsam, is a safe and excellent application, and daily rubbing the
parts very gently with a soft glove, or with the warm hand.
