h again increasing in frequency of occurrence and intensity if the
patient has been unduly exposed to cold or damp, or if the weather is
very changeable.

Children suffering from whooping-cough should have a light nourishing
diet and only go out when the weather is mild and warm.

_Medicines_. Aconitum napellus in the very commencement of the
disorder, followed by Ipecacuanha and Nux vomica when the second stage
is just approaching and during its continuance. These medicines may be
continued if necessary during the third stage.

959. Worms.

The presence of worms is indicated by irritation of the membrane of
the nose, causing the child to thrust its finger into the nostrils; by
irritation of the lower part of the body; by thinness, excessive
appetite and restlessness in sleep. Children suffering from worms
should eat meat freely and not take so much bread, vegetables, and
farinaceous food as children generally do. They should have as much
exercise as possible in the open air, and be sponged with cold water
every morning. The worms that mostly trouble children are the thread
worms, which are present chiefly in the lower portion of the
intestines, and the round worm.

_Medicines, &c_. Administer an injection of weak salt-and-water, and
give Aconitum napellus, to be followed by Ignatia and Sulphur in the
order in which they are here given. These are the usual remedies for
thread worms. For round worms, whose presence in the stomach is
indicated by great thinness, sickness and discomfort, and pain in the
stomach, Aconitum napellus, Cina, Ignatia and Sulphur are given.

960. Extent of Doses in Homoeopathy.

Homoeopathic medicines are given in the form of globules, pilules, or
tincture, the last-named being generally preferred. The average doses
for adults are from half a drop to one drop of the tincture given in a
tablespoonful of water, from two to four pilules, or from three to six
globules. In using the tincture it is usual to measure out a few
tablespoonfuls of water and to add to it a certain number of drops
regulated by the quantity of water that is used. For children medicine
is mixed at the same strength, but a less quantity is given. The
proper quantity for a dose is always given in books and manuals for
the homoeopathic treatment of disease. Small cases of the principal
medicines used in homoeopathy can be procured from most chemists,
