Sixteen hundred years before the times of this great Naturalist, PLUTARCH, in his valuable work on the education of children, had recommended the formation of their constitution as a point of the highest importance. “No care (says he) should be neglected that can contribute to the elegance and vigor of the body:” (the excesses of which I am treating are detrimental to both the one and the other;) “for” (adds he) “the foundation for a healthy old age is to be laid in youth: temperance and moderation at this early time of life, are a passport to a happy latter season[124].” To the account of the preceding case, in which the success appears due to the bark, I shall subjoin another, in which the cold bath was the principal remedy. A young man of a bilious constitution, seduced to libidinous practices from the age of ten years, had always been, from that time, weak, languishing, and of an ill habit of body: he had had some bilious disorders, which it had been very difficult to cure; he was extremely lean, pale, feeble, melancholic. I prescribed for him the cold bath, and a powder of cream of tartar, martials, and a very little cinnamon. In less than six weeks he acquired such a strength as he had never before known. One great advantage of the Spaw-waters and of the bark is, that the use of them agrees with milk, and suffers it to pass. The Spaw-waters are not the only ones that have this property. HOFFMAN prescribed asses milk, with a third of Seltzer-water. M. DE LA METTRIE has preserved to us a curious observation of M. BOERHAAVE; speaking of the Duke of ——, “This amiable Duke (I translate literally) had thrown himself out of the nuptial paradise; I brought him into it again by the use of Spaw-waters with milk[125].” A weakness of the stomach which causes the digestion to be too slow; acids; the want of activity in the bile; the obstructions in the intestines of the abdominal region, are the principal causes that hinder the digestion of the milk, and counter-indicate its use. The waters which remedy all these causes cannot but facilitate the digestion; and the bark, which fulfils the same indications, may also be very well combined with the milk. These remedies may be employed, either precedently, to prepare the passages, which is almost always necessary, or at the same time.
