How sure should we be of curing the disorders of men of learning, if it were possible to lull thought asleep. Here generous wines are of great service, provided the lungs are still unaffected, and a slow heat does not burn up the veins. Wholesome meats, and well boiled aliments, are of great service: milk is likewise of great service, provided the stomach is able to bear it. Riding is also useful. And it may be beneficial to purge away the peccant matter by some gentle, strengthening remedy. BACON recommends rhubarb. CELSUS, with more reason as I apprehend, recommended aloes, the use of which is of great service to the learned. Let them not, however, abuse an excellent remedy; for, though purges are sometimes necessary, they are dangerous when too frequently used: for the body begins to be disused to nourishment, and must of consequence grow weak. But beware, you sick men, of too violent purging remedies; because, as the intestines are often covered with mucus, this mucus is generally soft, and easily removed; when it is removed, a softer sort succeeds in its place; this badly defends the villous coat of the intestines; and, when it is left without defence, it either occasions incessant pains, or should be continually fomented by the tenderest sort of food. The Peruvian bark or kinkina is here of the greatest efficacy imaginable; in this case there is not a better remedy; it restores digestion, strengthens the vessels, compresses the fluids, promotes secretions, and, above all, perspiration, repairs the strength of the nerves, and quells false motions. One of our most eminent geometricians soon repaired his wasted powers by a large draught of the decoction of kinkina, which he had constantly by his side.
