96 ABNORMAL CONDITIONS OF THE GENERATIVE ORGANS. 



but the testes have not descended. One kidney is pre- 

 served ; it is much tabulated from arrest of development.

423. The lower part of the trunk of a Human foetus at about the 



sixth month of gestation, with complete ectopia of the 

 bladder. The penis is similar to that of the last prepara- 

 tion. The kidneys and ureters are preserved ; they are 

 much atrophied. The orifices of the latter are marked by 

 bristles. 



424. A Human female pelvis from an adult, aged 39 years. 



The pubic bones are separated from each other to the 

 extent of five inches, and the interval is occupied by a 

 ligamentous band. The woman from which this pelvis 

 was taken was the subject of complete ectopia of the 

 bladder (see next preparation) . The pelvis has evidently 

 been much modified by the manner in which the weight 

 of the body is thrown upon the sacrum, the pubic bones 

 being reduced by atrophy and their symphysis widely 

 separated. Presented by C. Mayo, Esq. 



425. A plaster cast of the bladder and external generative 



organs of the same individual. 



This cast is in the cast-room.

C. Of the Urino-generative Tract. 



The conditions commonly known as hermaphrodism are 

 chiefly dependent on various forms of arrested development of 

 the urino-generative tract. Those which affect the male are 

 classified in the following pages under the terms hypospadias 

 and androgyny, and those which affect the female under the 

 term gynandry. 



Hypospadias is the slightest form of arrest in the urino- 

 generative tract in the male, but no definite line can be drawn 

 anywhere between the slightest degree of hypospadias and the 

 most highly abnormal form of androgyny ; a series of perfectly 

 transitional malformations exist between these extremes. Simple 

 hypospadias consists in the defective closure of the anterior part 

 of the urethral canal below, so that the urethra opens at a dis- 

 tance from the extremity of the penis, although it is continued 

 as an open groove to its normal termination. In those animals
