Jonathan Swift: Gulliver's Travels

PART IV--A VOYAGE TO THE COUNTRY OF THE HOUYHNHNMS. 6. CHAPTER VI. (continued)

"Their fundamental is, that all diseases arise from repletion; whence they conclude, that a great evacuation of the body is necessary, either through the natural passage or upwards at the mouth. Their next business is from herbs, minerals, gums, oils, shells, salts, juices, sea-weed, excrements, barks of trees, serpents, toads, frogs, spiders, dead men's flesh and bones, birds, beasts, and fishes, to form a composition, for smell and taste, the most abominable, nauseous, and detestable, they can possibly contrive, which the stomach immediately rejects with loathing, and this they call a vomit; or else, from the same store-house, with some other poisonous additions, they command us to take in at the orifice above or below (just as the physician then happens to be disposed) a medicine equally annoying and disgustful to the bowels; which, relaxing the belly, drives down all before it; and this they call a purge, or a clyster. For nature (as the physicians allege) having intended the superior anterior orifice only for the intromission of solids and liquids, and the inferior posterior for ejection, these artists ingeniously considering that in all diseases nature is forced out of her seat, therefore, to replace her in it, the body must be treated in a manner directly contrary, by interchanging the use of each orifice; forcing solids and liquids in at the anus, and making evacuations at the mouth.

"But, besides real diseases, we are subject to many that are only imaginary, for which the physicians have invented imaginary cures; these have their several names, and so have the drugs that are proper for them; and with these our female Yahoos are always infested.

"One great excellency in this tribe, is their skill at prognostics, wherein they seldom fail; their predictions in real diseases, when they rise to any degree of malignity, generally portending death, which is always in their power, when recovery is not: and therefore, upon any unexpected signs of amendment, after they have pronounced their sentence, rather than be accused as false prophets, they know how to approve their sagacity to the world, by a seasonable dose.

"They are likewise of special use to husbands and wives who are grown weary of their mates; to eldest sons, to great ministers of state, and often to princes."
