    urine did not range above 1019 or 20°, but litbates were very abundant. No doubt under the light of former physiological knowlege it was naturally expected that an increased excretion of urea would take place as an inevitable result of tissue metamorphosis in chorea. Present teaching, however, shows us that we ought neither to have found nor sought for such increase of urea in chorea. On this matter see the ‘Ed. Med. Journal/ Eeb. 1866, wherein Dr. K. Anderson describes the daily amount of urea in the second week of typhus, as being “ decidedly below the standard of health, notwithstanding that the patients were in a state of high fever with the temperature and pulse much above the normal state.” See also the experiments of Bischoff, and Yoit, and Pick, and Wislicenus of Zurich, corroborated by Pro- fessor Erankland, from which it appears that muscular power is derived from the oxidation of hydro-carbonaceous material mainly, though not entirely. Prankland thinks the mechanical force of the muscles is derived from the oxidation of matters contained in the blood, and not from that of the muscles themselves. Dr. Parkes (see ‘Proc. Eoyal Soc./ Jan., 1867), from experiments, came to the conclusion that, unless nitrogen be found to disappear through the skin, it must be supposed that muscular force is derived from the carbo-hydrates, the amount of nitrogen excreted during active exercise being lower than that excreted during a period of rest, though in the period of rest following work, it is slightly increased. Pettenkofer and Yoit noticed recently that muscular work seems to have no influence on the amount of urea excreted. I will now add the details of a case which was not under my care, but of which I have been favoured with the following notice. I have alluded to it at foot-note to page 26. It was that of a boy who lived in Derbyshire. He had had some kind of “ fever” and was inefficiently nursed, and, subse- quently, became severely affected by chorea; during sleep he was perfectly quiet, but on waking would at once commence sing^g and shouting vociferously, and jumping and “ working about” as friends described it, until he was quite exhausted. He would jump violently, and scream loudly, and by jerking motions eject the spittle to an enormous distance. Por some time he was unable to swallow any substance, and at last became in consequence “ so frantic for^food ” that he swallowed everything whole directly he put it into his mouth. In this condition he continued for several weeks, and was treated by T. Eentem, Esq., of Eyam, who, in addition to other treat- ment, applied a blister at the back of the neck. At last, it was deter- <# mined to take him to the Sheffield Infirmary. To the boy's delight (expecting cure at the Infirmary), a carriage was procured for him, and he was conveyed thither a distance of several miles. He jumped
