Ultimately it was passed into the bladder and voided in theurine. This is by no means an uncommon occurrence, and should be keptwell in mind when we have to consider the question of operative interferencein a case where the presence of a stone has been demonstrated in the courseof the ureter. If thesymptoms are notacute, all smallureteric calculi shouldbe given every facilityto pass into thebladder before aserious operationcontemplated. ^Vhattermed a stone in the ureteris well illustratedby a case occurringin the practice of Dr.Thurston Holland ofLiverpool, where alarge stone was foundto occupy a positionin the lower ureterand pelvis of thekidney alternately.At the operation it was found that the ureter was dilated to an enormousextent. Urinary Calculi.—3. In the Bladder.—A vesical calculus may beformed of almost any of the urinary deposits met with, and each has its owncharacteristics.

On section it is distinctly laminated with a smoothor slightly undular surface of a brownish colour. It may be crusted mthphosphatic material. A pure uric-acid calculus gives a faint shadow radio-graphically. (6) The urate of ammonium calculus is of a similar structure, but oflighter colour. (c) Oxalate of lime calculus is a rough irregular body, not infrequentlytuberculated or even spiculated. It is extremely hard and dense, of areddish-brown colour, or sometimes black, owing to admixture \nth blood.It is rarely of great size, on account of the irritation caused by its presenceand its slowness of growth. (d) A pure phosphatic calculus is somewhat rare, but any stone or foreignbody is certain to become coated with a phosphatic deposit when chroniccystitis has resulted in alkaline decomposition of the urine. (e) Cystin forms the base of a rare calculus. (
