    12G or water. Urine from which pellicles of kiestien have formed appears to contain no albumen, and but very rarely casein. It is generally neutral or alkaline and occasionally acid; while the pellicle itself is stated never to become mouldy. 141. Fatty matter, (667t,) occasionally met with in the urine, may also be detected with the micros- cope, and by its characteristic globules; and Hke- wise by the yellow solution that collects on the surface of the urine when ether is added to it, and which yields fat globules on evaporation. 142. Urostealith.—This is the name given by Dr. F. Heller, to a pecuhar concretion that was passed by a patient while suffering from symptoms of calculus in the bladder, and which he found to consist of a particular kind of fatty matter. These concretions, when first passed are soft, but become hard by drying. They are then brittle, have some- what the appearance of wax, and a greenish yellow hue when viewed by transmitted light. When heated they melt, then swell and burn with a characteristic pungent odour, something like that of gum benzoin, leaving an abundant ash. Uros- tealith is soluble in ether, from which it can be obtained by evaporation, but is insoluble in water, and nearly so in alcohol. It is also soluble in nitric acid with effervescence, a colourless substance being formed j and combines readily with alkalies, which will separate it from its etherial solution.
