![of oxalate of lime upon their exterior; while, no doubt, the greater number escape with the urine, and give no trouble. Such small bodies would easily become entangled in the mucus of the mucous membrane, and might remain in the pelvis of the kidney without exciting any disturbance until they had grown so large as to cause great inconvenience. If some of them passed down the ureter into the bladder, and happened to be retained for some time in tliis viscus, in a case where the urine contained much oxalate, they might increase in size until too large to escape by the urethra. It is, therefore, of great importance that cases in which these dumb-bell crystals are deposited should be very carefully watched. This obser- vation is of some interest also as showing the chemical composition of the dumb-bells, which has long been a disputed point. As I have before stated, many small uric acid calculi, which appear to be composed entirely of this substance, will be found upon careful examination to possess a nucleus consisting of oxalate of lime, and not unfrequently by the action of liquor potassae well-defined dumb-bell crystals may be obtained. These are insoluble in potash, and also in acetic acid. I have obtained from several specimens fragments of a mass larger than that represented in Fig. 124, and no doubt formed in the same manner. From recent analyses I have made, I have been led to the conclusion that the dumb-bell crystals form the nucleus, around which the uric acid is deposited, more frequently than any other substance. I have not detected oxalate of lime in the centre of the small renal calculi composed of phosphate of lime which I have subjected to examination. Ox THE Relative Frequency of the Occurrence or the DlFFERE]>fT CaLCULL 462. FrecLuency of Occurrence of different kinds of Calcxili.— It is often very difiicult to ascertain why certain varieties of calculi should be found in greater proportion in some parts of the country than in others. The question is one of great interest in connection with the consideration of conditions under which the formation of urinary calculi occurs. In the collection of calculi at Guy's Hospital the proportion composed of phosphate of lime is as 1:29; at Bartholomew's as 1:32^; while in I^orwich it is as l:132f; and in Bristol as 1:155.
