When empty and viewed in mesial section it may presentone of two shapes. In the large majority of specimens figured, it formswith the urethra a Y shape on sagittal mesial section. The oblique legs ofthe Y may be about equal in size, or the posterior may be shorter (, 34). This form is so common that it has been accepted hitherto byall authors as the normal one.

In such cases it is oval in shape, corrugated, and firm to the touch. This latter shape is the one always found in the lower animals, such as the rabbit and dog, and is the only one seen in the human foetus. If, therefore, the pelvic floor of a woman be viewed on its peritoneal aspect, the fundus ofVol. I.—3 34 MANUAL OF GYNECOLOGY. the empty bladder will be found to be almost always large and concave,while in a few cases it is small and convex. In the former case, the innersurface of the upper segment of the bladder, large in area, is in contactwith the surface of the lower segment; in the latter, the anterior and pos-terior inner walls, small in area, touch one another. It is probable that when the bladder has the Y shape o
