    most numerous near the neck of the bladder, and the mhole surface is covered with a spheroidal epithelium. IThe vesical mucus has, it is said, an alkaline reaction, oand contains alkaUne and earthy phosphates. The mem- tbrane—having these characters—is loosely attached to tthe muscular coat, by means of the sub-cellular layer; sso that when the bladder is empty, the surface generally iis thrown into small internal folds or wrinkles, and when cdistended, there is some tendency to protrusion in the iintervals of the muscvilar bands. The inferior fundus is the most capacious and de- fpendent part of the bladder; in front, it presents a small ctriangular space—the trigone vesical; situated imme- cdiately behind the orifice of the urethra, the apex of tthis space is directed forwards to that orifice, and the tbase is a transverse line slightly curved forwards, between ithe orifices of-the two ureters, which form the posterior wangles of the space; while the sides are marked by two 1 linear ridges passing obliquely backwards and outwards I ffrom the urethra to the ureters, and which correspond Itto two small fasciculi of muscular fibres—the muscles cof the ureters, lying under the mucous membrane. These iimuscles arise from behind the middle lobe of the pro- sstate, and pass to the obhque slit-like openings of the lureters ; they may, therefore, so act upon these openings sas to maintain their obliquity, and thus prevent any treflux of urine into the tubes; or, by drawing their i apertures downwards, may facilitate the flow of urine iinto the bladder. The trigone—having the boundaries ■ already noticed—corresponds to the triangular space at t the base of the bladder, which Hes between the prostate
