This is a kind of inflammation of the brain produced by exposure to the strong heat of the sun. It is quite common in India, and other warm climates. The head may be bathed with brandy, and a small quantity given internally occasionally, until the prominent symptoms are relieved.

Camphor may be given, one drop at a dose, at intervals of five or ten minutes, to be followed after four or five doses have been taken, by belladonna, alone or in alternation with carb. v., or Zachesis, half an hour apart.
