The uri¬ nary bladder and its channels are similar in their composition to the intestines; but the mucus of the bladder, such as it is deposited w ith the urine, is very unlike the mucus in other places. It is almost completely pellucid, forming’ small grains, which, when gathered on a tiller, leave a slip¬ pery and colourless mucus, wliicli, however, often becomes red in drying, and shows signs of con- toi»wng uric acid.
