The case is very similar to what Dr. Whytt relates of himself, in his Observations on Nervous, Hysteric, and Hypochondriac Disorders, 8vo. 1767[85]; by which, Dr. Cullen, in p. 10 of his Clinical Lectures, says, “he has done more than all his predecessors.”

Mr. Waller has written a very sensible Essay on the Nightmare—those who are much afflicted with it, cannot lay out 3s. 6d. better, than in buying his book—12mo. 1816. He says, “it most frequently proceeds from acidity in the Stomach, and recommends Carbonate of Soda, to be taken in the Beer you Drink at dinner.” He tells us “he derived his information, as to the cause, and cure of this distressing disorder, from a personal acquaintance with it for many years.”

How devoutly it is to be wished that all Authors would follow good old Sydenham and Mr. Waller’s example,—and give us a register of the progress of those chronic complaints which they have themselves been afflicted with, and the regimen, &c. which they have found most effectual to alleviate and cure them;—and, instead of what they think,—write only what they know,—as the pains-taking Sanctorius—Spallanzani—Bryan Robinson,—and the persevering and minutely accurately observing Dr. Stark have in their Dietetical Experiments.

Dr. Whytt has immortalized himself by the candid relation of his own infirmities, and his circumstantial account of the Regimen, &c. which enabled him to bear up against them,—which forms the most valuable collection of observations on Nervous Complaints, that experience and liberality have yet presented to the public.

One page of PERSONAL EXPERIENCE, is worth folios of theoretic Fancies,—or Clinical Cases, which can only be illuminated by the twilight of conjecture:—they may be faithful narratives of the accounts given by Patients, yet, as these are very often imposed upon by their imagination attributing effects to very different causes than those which produce them, they are often very inaccurate deductions.

The Delicate and the Nervous, will derive the greatest advantage from keeping a Register of their Health,—they should note, and avoid whatever disagrees with them,—and endeavour to ascertain, what kind and quantity of Food—Exercise—Occupation and Pleasures, &c. are most agreeable to their constitution, and take them at those regular periods which appear most convenient to them. However this advice may excite the smiles of those who are swelling “in all the pride of superfluous Health,” such methodical movements will considerably improve the enjoyment, and prolong the life of the Valetudinary and the Aged: for whom, Instinct is the best Guide in the choice of Aliment.

None but the most obstinately ignorant Visionary, would dream of laying down absolute Rules[86] for governing the caprice and whims of the infirm Stomachs of Crazy Valetudinarians. Codes of Dietetics[87] are almost useless,—the suggestions of Reason are often in direct opposition to the desires of Appetite.

In most matters regarding the adjustment of that supreme organ of existence,—the Stomach,—“honest Instinct[88] comes a Volunteer.”—Ventriloquism seldom falls to make out a fair title, to be called “unerring.” A due respect to the suggestions of Instinct, every Invalid will find highly advantageous,—natural longing has frequently pointed out Food—by which Acute Diseases have been cured, when the most consummate medical skill was at fault, and Life at its lowest ebb.

It is needless to insist upon the importance of Diet and Regimen in Chronic Disorders.

Be content with One[89] Dish,—from want of submission to this salutary rule of Temperance—as many men dig their Grave with their Teeth, as with the Tankard;—Drunkenness is deplorably destructive, but her demurer sister Gluttony destroys an hundred to her one.
