SUNSTROKE, COUP-DE-SOLEIL.

Sunstroke, or coup-de-soleil, has been referred to under local diseases of the nervous system, at page 173. There are two kinds of it; one apoplectic in its nature, affecting persons of plethoric habit, and especially those who indulge in stimulants; the other syncopal in its nature, and affecting the feeble. The first is true sunstroke, as I should define it strictly, from what I have seen. The affection is rare in this country, except, in summer, when the heat is intense. It then happens to persons who go out without being protected from the direct rays of the sun. I have seen in stances of it in adults of both sexes, and twice in children. The person affected is seized with a sudden giddiness or vertigo, fol lowed by unconsciousness and want of power in the limbs.

In the apoplectic variety of the disease the face is livid, the veins swollen, the temperature of the body raised, the heart labor ing, and the breathing heavy and stertorous; signs which in fatal cases continue until death. When recovery occurs it is often very rapid.

The syncopal variety is, according to my experience, rather an extreme faintness or oppression from heat than the effects of a sudden wave of heat. It is attended with coldness, faintness, clammy perspiration, and often with convulsion or hysteria, the attack lasting for several hours, and being followed by some reac tive fever and a long-continued dyspepsia. I have known it to be succeeded by partial paralysis of the right side of the body, but it is much less serious, both immediately and subsequently, than the apoplectic form of the malady.
