The _intestinal_ state of our summer and autumnal disease requires several specific means to prevent it, different from those which have been advised to defend the blood-vessels from fever. Unripe and decayed fruit should be avoided, and that which is ripe and sound should not be eaten in an excessive quantity. Spices, and particularly Cayenne pepper, and the red pepper of our country, should be taken daily with food. Mr. Dewar, a British surgeon, tells us, the French soldiers, while in Egypt, carried pepper in boxes with them, wherever they went, to eat with the fruits of the country, and thereby often escaped its diseases. The whole diet, during the prevalence of intestinal diseases, when they are not highly inflammatory, should be of a cordial nature. A dysentery prevailed, a few years ago, upon the Potomac, in a part of the country which was inhabited by a number of protestant and catholic families. The disease was observed to exist only in the former. The latter, who ate of salted fish every Friday, and occasionally on other days of the week, very generally escaped it. In the year 1759, a dysentery broke out in the village of Princeton, in New-Jersey, and affected many of the students of the college. It was remarked, that it passed by all those boys who came from the cities of New-York and Philadelphia. This was ascribed to their having lived more upon tea and coffee than the farmers' sons in the college; for those cordial articles of diet were but rarely used, six and forty years ago, in the farm houses of the middle states of America. I mentioned formerly that the cordial diet of the inhabitants of our cities was probably the reason why the dysentery so seldom prevailed as an epidemic in them. Another means of preventing the dysentery is, by avoiding costiveness, and by occasionally taking purging physic, even when the bowels are in their natural state. A militia captain, in the Pennsylvania service, preserved his whole company from a dysentery which prevailed in a part of the American army at Amboy, in the year 1776, by giving each of them a purge of sea-water. He preserved his family, and many of his neighbours, some years afterwards, from the same disease, by dividing among them a few pounds of purging salts. It was prevented, a few years ago, in the academy of Bordentown, in New-Jersey, by giving all the boys molasses, in large quantities, in their diet and drinks. The molasses probably acted only by keeping the bowels in a laxative state. As the dysentery is often excited by the dampness of the night air, great care should be taken to avoid it, and, when necessarily exposed to it, to defend the bowels by more warmth than other parts of the body. The Egyptians, Mr. Dewar says, tie a belt about their bowels for that purpose, and with the happiest effects.
