    out of the notch and then suddenly turns backward under the posterior end of the gland, passing between it and the capsula renalis ; it then takes its course directly backward, a little distance laterally removed from the bodies of the lumbar vertebrae, crossing ob- liquely the psoas parvus and afterwards the great iliac vessels ; here it enters the pelvis by a sweep upward and outward (embracing within its concavity the vas deferens and ligamentum rotundum) and becomes included within the fold of the ligamentum latum, by which it is conducted to the lateral and superior part of the bladder; latterly, it runs in close connection from the middle of the bladder half-way to its neck and then imperceptibly vanishes between its tunics. Though we insensibly lose sight of the tube however it does not end here, for after having obliquely pene- trated the muscular coat it travels onward for the space of an inch between that and the internal coat, and at length terminates by piercing the latter in the same oblique line of direction. The diameter of the ureter near its origin is equal to that of a large-sized black-lead-pencil, from which it so insensibly dimi- nishes in calibre throughout its course that we are only assured of the fact by comparing the anterior with the posterior portion. That part of the tube not included within the broad ligament is invested with cellular and adipose tissue which binds it down in its course. It is composed of two tunics. The external one is thick, resisting, and longitudinally fibrous, and is believed to be muscular: the internal is soft and fine in its tex- ture ; is commonly rugose lengthwise ; is loosely adhe- rent to the other ; and is constantly besmeared within with a mucous secretion to shield it from the urine.
