used when mumps
follow an attack of measles.

954. Nettlerash.

This rash, so called because in appearance it resembles the swelling
and redness caused by the sting of a nettle, is generally produced by
a disordered state of the stomach.

_Medicines_. Aconitum napellus, Nux vomica, or Pulsatilla, in
ordinary cases; Arsenicum is useful if there be much fever; Belladonna
if the rash is accompanied with headache.

955. Piles.

The ordinary homoeopathic remedies for this painful complaint are Nux
vomica and Sulphur.

956. Sprains.

Apply to the part affected a lotion formed of one part of tincture of
Arnica to two of water. For persons who cannot use Arnica, in
consequence of the irritation produced by it, a lotion of tincture of
Calendula may be used in the proportion of one part of the tincture to
four of water.

957. Teething.

Infants and very young children frequently experience much pain in the
mouth during dentition, and especially when the tooth is making its
way through the gum. The child is often feverish, the mouth and gums
hot and tender, and the face flushed. There is also much running from
the mouth, and the bowels are disturbed, being in some cases confined,
and in others relaxed, approaching to diarrhoea.

_Medicines_. These are Aconitum napellus, in ordinary cases; Nux
vomica, when the bowels are confined; Chamomilla, when the bowels are
relaxed; Mercurius, if the relaxed state of the bowels has deepened
into diarrhoea; Belladonna, if there be symptoms of disturbance of the
brain.

958. Whooping-Cough.

This disease is sometimes of long duration, for if it shows itself in
the autumn or winter months, the little patient will frequently retain
the cough until May or even June, when it disappears with the return
of warmer weather. Change of air when practicable is desirable,
especially when the cough has been of long continuance.

In this cough there are three stages. In the first the symptoms are
those of an ordinary cold in the head and cough. In the second the
cough becomes hard, dry and rapid, and the inhalation of the air,
after or during the paroxysm of coughing produces the peculiar sound
from which the disease is named. In the final stage the cough occurs
at longer intervals, and the paroxysms are less violent and ultimately
disappear. In this stage the disease is subject to fluctuation, the
