I shall only add, that by keeping the blood cool as well as clean, is to be understood, not only moderation in diet, but to feed most on cooling food made of wheat, barley, oat-meal, rice, and ripe apples, as also on milk, which, joined with oat-meal, is the chief food of those lusty and strong men, the Highlanders of Scotland, who abound in children, as Dr. Cheyne tells us in his _Treatise of the Gout_, p. 108. edit. 4. which demonstrates milk and oat-meal to be a most strengthening food, and such as keeps the blood in due order; so that therewith men may subsist, tho’ they abstain from beef, pork and venison, and all other meats hard to digest, and drink water as the highlanders do: Of the efficacy of which cooling milk-diet the said Dr. Cheyne gives a notable instance in a doctor that lived at Croyden, p. 103. who had long been afflicted with the falling-evil; for, by slow observation, he found the lighter his meals were, the lighter were his fits. At last he also cast off all liquids but water, and found his fits weaker, and the intervals longer; and finding his disease mend, as its fewel was withdrawn, he took to vegetable food, and water only, which put an entire period to his fits without any relapse: But finding that food windy to him, he took to milk, of which he drank a pint for a breakfast, a quart at dinner, and a pint for supper, without fish, flesh, bread, or any strong or spirituous liquor, or any drink but water, with which he lived afterwards for fourteen years, without the least interruption in his health, strength or vigour, but died afterwards of a pleurisy. Which is a confirmation of what Dr. Cook did affirm, of the possibility of curing diseases by a diet only, that is temperate and cooling; of which milk is a part, as are also the roots and seeds of vegetables, such as potatoes, turnips, wheat, rice, barley, oat-meal, and full ripe fruit. In short, temperance or a spare diet, void of dainties, never was injurious to the strongest constitution; and, without it, such as are weak and sickly cannot long subsist; for the more such persons eat and drink, the more weak and disordered they will still find themselves to be: so that if the strong despise temperance, yet the comfort of weak, sickly and pining people, does depend entirely upon their constantly observing it; which, when they are accustomed to it, will be easy to do: So that they will deny all intemperate desires with as great pleasure, as they before delighted in what is falsely stiled good eating and drinking; for nothing of that is good, which is injurious to health. It is custom only that makes men hanker after gluttony and drunkenness, and a contrary custom will make men abhor it as much: And therefore it is a wonder the rich do not strive to attain to it; for _A fatal error ’tis in men of wealth, To feed so high as will destroy their health._
