857. _Worms._--There are three species of worms which infest the intestines: namely, the flat worm, or tænia; the long, round worm, lumbrici; the short, round worm, or ascarides. The tænia is of rare occurrence when compared with the lumbrici or ascarides, but more difficult to remove. Full doses of sulphate of iron, with occasional active doses of calomel, force them to retire. The lumbrici are destroyed by repeated doses of calomel and scammony. The ascarides, being found in the lowest portion of the intestines, are easily removed by injections of lime-water, or a solution of aloes. Parents who would preserve their children from worms, ought to allow them plenty of exercise in the open air; to take care that their food be wholesome and sufficiently solid; and, as far as possible, to prevent their eating raw herbs, roots, or green trashy fruits. It will not be amiss to allow a child who is subject to worms, a glass of red wine after meals; as every thing that braces and strengthens the stomach, is good both for preventing and expelling these vermin. In order to prevent any mistake of what I have here said in favor of _solid_ food, it may be proper to observe, that I only made use of that word in opposition to _slops_ of every kind; not to advise parents to cram their children with meat, two or three times a-day. This should only be allowed at dinner, and in moderate quantities, or it would create, instead of preventing, worms; for there is no substance in nature which generates so many worms as the flesh of animals, when in a state of putrefaction. Meat, therefore, at the principal meal, should always be accompanied with plenty of good bread, and young, tender, and well-boiled vegetables; especially in the spring, when these are poured forth from the bosom of the earth in such profusion. They promote the end in view, by keeping the body moderately open, without the aid of artificial physic. The ripe fruits of autumn produce the same effect; and, from their cooling, antiputrescent qualities, are as wholesome as the unripe are pernicious. I also very earnestly conjure parents not to take the alarm at every imaginary symptom of worms, and directly run for drugs to the quack, or apothecary. They should first try the good effects of proper diet and regimen, and never have recourse to medicines till after unequivocal proofs of the nature of the complaint. Honey and milk are very good for worms; so is strong salt water; likewise, powdered sage and molasses taken freely.
