There are also cases whichmay be noticed here, in which thepatients continue to lose groundalthough the quantity of sugarlessens, and in which the sub-stance known as inosite or muscle-sugar is found in the urine (). It increases in quantity asthe sugar lessens, and at last asmuch as eighteen and twentygrammes of pure inosite havebeen procured from the days. * Inosite or muscle-sugar, crystallized partly from alcohol and partly from water(after Funke). 182 SPECIAL PATHOLOGY DIABETES MELLITUS. urine. The inosde may be obtained in the form of colorless prismaticcrystals, which are efflorescent. It does not reduce the oxide ofcopper to the state of suboxide, as is the case with diabetic sugar andgrape-sugar; and it is said to have not quite the same composition asthe latter substance, but is represented by C^ Hg O^; so that one atomoi grape sugar would thus represent six atoms of inosite. It may bedetected by evaporation of the suspected fluid nearly to dryness ina platinum basin, when, if a little ammonia and chloride of calciumbe added, a rose color is produced, especially if the mixture be againconcentrated by evaporation. M. Hohl records a case of diabetesin which, while the proportion of sugar gradually diminished, theinosite gradually increased in amount till upwards of 300 grainswere passed in th
