The transparent spot in the centre is caused by reflection from the sides of the octohedron. Urine depositing oxalate of lime is generally of about the normal specific gravity. It oc- casionally has a light greenish hue. The de- posit when allowed to collect in a glass vessel is rarely seen otherwise than as a floating cloud collecting at bottom, and closely re- sembling the appearance which would be put on by the presence of an excess of the mucus of the bladder natural to the urine. It has recently been stated, by Dr. Frick, of Baltimore, that the crystalline masses, in the form of dumb-bells, described by Dr. Bird as consisting of oxalate of lime, are really com- posed of lithic acid. It is true that lithic acid occasional}' assumes a form more or less re- sembling the dumb-bells figured by Dr. Bird, but scarcely so nearly as to be easily mis- taken for them. Dr. Harris Wilson has also recently shown that lithic acid may be made to assume a form nearly approaching in character to the dumb-bells. I have ex- amined, with Dr. Bird, some specimens of the dumb-bells, and am satisfied that those we operated upon were composed of lime in com- bination with an organic acid. In a paper recently published by Dr. Bird in the Hedical Gazette, some reasons are given by him for believing that acid to be the oxaluric, and not the oxalic, and there would appear good grounds for the adoption of that opinion. DEPOSIT OF CYSTIIS'E. This substance, which is not one of the ingredients of normal urine, is an organic bod}', occasionally existing as a deposit in the form of flattened hexagonal plates. Under the microscope it presents the following ap- pearances (fig. 796). 0 CARBONATE OF LIME DEPOSIT. This rare deposit exists in the form of spher
