The portion of earthy and alkaline salts, which urine contains, is also very considerable, whereas in the blood it is but small. The different sediments, which the urine precipitates whilst cooling*, I found to be either solely the mucus of the bladder, whieh is alwaysi present in urine, partly suspended, and partly dis¬ solved, or a combination of this mucu;^ with the V- uric acid; but it does not contain earthy plios- phatcs. I have endeavoured to show the neces¬ sity of making* a distinction between the me¬ chanical sediment, which is abundant in the ca- tarrhus vesicce, and comes from the bladder, and that, which takes place when the bone-earth k
