106 ABNORMAL CONDITIONS OP THE GENERATIVE ORGANS. 



D. Of the Uterus, 

 a. Double uterus. 



The Miillerian ducts in some animals (the Didelphia) remain 

 distinct,, in others partially distinct, forming the uterine cornua; 

 or they unite to form the cavity of the uterus,, their distinct 

 ends forming the tubes, as in Man. Sometimes in the latter 

 the union either fails partially or entirely, giving rise to a 

 corniculate or double uterus. The vagina is also divided by a 

 septum in extreme cases. 



450. The uterus of a Cow, in which there is a partial septum 



below the cornua. The body of the uterus contains a 

 single cavity, from which the deformed immature fetus 

 No. 261 was taken. There are two cervices and a 

 double os. Hunterian. 



451. The vagina and internal generative organs of a Human 



adult female. The vagina is completely divided by a 

 strong muscular septum. The uterus is double, and 

 each lateral half is quite separate from the other ; they 

 have been bent over laterally in making the preparation. 

 There is a single tube and ovary to each uterus. The 

 cavity of the vagina and uteri are laid open.

452. The orifice of the vagina of a Human adult female; it is 



divided by a strong muscular septum, commencing im- 

 mediately above the urethra. The right nympha forms 

 a free process posteriorly, as if it had been dissected 

 from its attachment. 



453. A double Human uterus and vagina. One of the lateral 



uteri contains a full-time foetus; the other cavity is 

 considerably developed, measuring 4 inches in diameter. 

 The vagina is completely divided by a septum. The 

 bladder, the right side of the vagina, and both uterine 

 cavities are laid open. There is but a single Fallopian 

 tube to each uterus. Hunterian. 



Sometimes one lateral half of the uterus is undeveloped, 

 uterus unicornis ; sometimes the os or the vagina is occluded. 

 It is uncertain whether such malformations should properly be 

 included in the present Class. .
