In his masterly article on "Heredity," Sedgwick quotes an instance of total absence of the uterus in three out of five daughters of the same family; two of the three were twice married.
Double uterus is so frequently reported that an enumeration of the cases would occupy several pages.

Bicorn, bipartite, duplex, and double uteruses are so called according to the extent of the duplication.

The varieties range all the way from slight increase to two distinct uteruses, with separate appendages and two vaginae.

Meckel, Boehmer, and Callisen are among the older writers who have observed double uterus with associate double vagina.

Figure 150 represents a transverse section of a bipartite uterus with a double vagina.
