"But the only conclusion I would draw from these historical facts is, that a low diet, or living on vegetables, will not destroy life or health, or cause nervous and cephalic distempers; but, on the contrary, cure them, as far as they are curable. I pretend to demonstrate from these facts, that abstinence and a low diet is the great antidote and universal remedy of distempers acquired by excess, intemperance, and a mistaken regimen of high meats and drinks; and that it will greatly alleviate and render tolerable the original distempers derived from diseased parents; and that it is absolutely necessary for the deep thinking part of mankind, who would preserve their faculties sound and entire, ripe and pregnant to a green old age and to the last dregs of life; and that it is, lastly, the true and real antidote and preservative from heavy-headedness, irregular and disorderly intellectual functions, from loss of the rational faculties, memory, and senses, and from all nervous distempers, as far as the ends of Providence and the condition of mortality will allow. "Let two people be taken as nearly alike as the diversity and the individuality of nature will admit, of the same age, stature, complexion, and strength of body, and under the same chronical distemper, and I am willing to take the seeming worse of the two; let all the most promising nostrums, drops, drugs, and medicines known among the learned and experienced physicians, ancient or modern, regular physicians or quacks, be administered to the best of the two, by any professor at home or abroad; I will manage my patient with only a few naturally indicated and proper evacuations and sweetening innocent alternatives, which shall neither be loathsome, various, nor complicated, require no confinement, under an appropriate diet, or, in a word, under the 'lightest and the least,' or at worst under a milk and seed diet; and I will venture reputation and life, that my method cures sooner, more perfectly and durably, is much more easily and pleasantly passed through, in a shorter time, and with less danger of a relapse than the other, with all the assistance of the best skill and experience, under a full and free, though even a commonly reputed moderate diet, but of rich foods and generous liquors; much more, under a voluptuous diet." But I am unwilling to dismiss this subject without inserting a few more extracts from Dr. Cheyne, to show his views of the treatment of diseases. And first, of the scurvy, and other diseases which he supposes to arise from it.
