2. After Bleeding, the Patient's Legs should be plunged into warm Water. This is one of the Applications that affords the most speedy Relief; and I have seen the Head-ach go off and return again, in Proportion to the Repetition, and the Duration, of these Bathings of the Legs. When the Disorder is highly dangerous, it will be necessary to treat the Patient with _Semicupia_, or warm Baths, in which he may sit up to his Hips; and in the most dangerous Degrees of it, even to bathe the whole Body: but the Water in this Case, as well as in Bathings of the Feet, should be only sensibly warm: the Use of hot would be highly pernicious. 3. Glysters made from a Decoction of any of the emollient Herbs are also very effectual. 4. The Patient should drink plentifully of Almond Emulsion No. 4; of Limonade, which is a Mixture of the Juice of Lemons and Water, (and is the best Drink in this Disease) of Water and Vinegar, which is a very good Substitute for Limonade; and of, what is still more efficacious, very clear Whey, with the Addition of a little Vinegar. These various Drinks may all be taken cold; Linen Cloths dipt in cold Water and Vinegar of Roses may be applied to the Forehead, the Temples, or all over the Head, which is equivalent to every other Application used upon such Occasions. Those which are the most cried up, are the Juice of Purslain, of Lettuce, of Houseleek, and of Vervain. The Drink No. 32 is also serviceable, taken every Morning fasting. Sec. 161. Cold Baths have sometimes recovered Persons out of such violent Symptoms, from this Cause, as have been almost quite despaired of. A Man twenty Years of Age, having been a very long Time exposed to the scorching Sun, became violently delirious, without a Fever, and proved really mad. After repeated Bleedings, he was thrown into a cold Bath, which was also frequently repeated; pouring cold Water, at the same Time, upon his Head. With such Assistance he recovered, though very gradually. An Officer who had rode Post for several Days successively, in very hot Weather, swooned away, immediately on dismounting; from which he could not be recovered by the ordinary Assistance in such Cases. He was saved however, in Consequence of being plunged into a Bath of freezing Water. It should be observed however, that in these Cases the cold Bath should never be recurred to, without previous Bleeding. Sec. 162. It is past Doubt, that if a Person stands still in the violent Heat of the Sun, he is more liable to be struck with it, than if he walks about; and the Use of white Hats, or of some Folds of clean white Paper under a black one, may sensibly contribute to prevent any Injury from the considerable Heat of the Sun; though it is a very incompetent Defence against a violent Degree of it.
