he began to suffer from hæmaturia. “This became,” he says, “afterwards habitual, as often as I either went along a way on foot, or drove in a carriage, no matter how slowly, over the paved streets. On an unpaved road, however, I might drive as far as I chose, and no such harm would occur.” He tried various remedies for this trouble without success. “I therefore made up my mind to try no further, and only guarded against the affection by avoiding as much as I could all motion of the body.” When his urine became bloody he was bled, and he took frequent doses of manna dissolved in whey as a laxative, and sixteen drops of laudanum in small beer at bedtime as a hypnotic. As to the regimen he observed, he says: “On getting out of bed I drink a dish or two of tea, and ride in my coach till noon, when I return home and moderately refresh myself (for moderation is well in all) with some sort of easily digestible meat that I like. Immediately after dinner, I drink rather more than a quarter of a pint of Canary wine to promote the concoction of the food in the stomach, and to drive away the gout from the bowels. After dinner I ride in my coach again, and (unless prevented by business) am driven out for two or three miles in the country for change of air. A draught of thin small beer serves for supper, and I repeat this even after I have gone to bed and am about to compose myself to sleep. I hope by this julep to cool and dilute the hot and acrid juices lodged in the kidneys, whereby the stone is occasioned.” He goes on to state that he prefers the “hopped small beer,” and “to prevent bloody urine I take care as often as I drive any distance over the stones to drink a free draught of this small beer upon getting into my coach, and also, if I am out long, before my return, a precaution which has always been sufficient.” Occasionally he suffered from what may be called a gastric crisis, and “in this case I drench myself with more than a gallon of posset, or else of this small beer: and, as soon as I have got rid of the whole by vomiting, take a small draught of canary wine with eighteen drops of the liquid laudanum, and, going to bed, compose myself to sleep. By this method I have escaped imminent death more than once.” In an attack of nephritic colic occurring in a patient of sanguine temperament, Sydenham took ten ounces of blood from the arm on the same side with the kidney affected. “After this a gallon of posset drink, wherein two ounces of marsh-mallow roots have been boiled, must be taken without loss of time, followed by the injection of the following enema: Marsh-mallow roots and lily-roots, of each one ounce; mallow-leaves, pellitory, bears’ breech, and chamomile flowers, of each a handful; linseed and fennugreek, of each half an ounce; water in sufficient quantity. Boil down to half a pint; strain; dissolve in the clear liquor two ounces each of kitchen sugar and syrup of marsh-mallow; mix and make into a clyster. After the
