according to Dr. Bruce, 5 had extra nipples, and out of 207 males there 

 were 19 such cases. The abnormality, it appears, is thus more com- 

 mon to the male sex. Dr. Dunglison mentions the case of an athletic 

 man 22 years old, who came in 1849, to the Jefferson Medical college 

 of Philadelphia, with his left mamma full of milk, for which he could 

 not account. In 1837 there was a colored man in Maiyland, who was 

 then 55 years old, and who possessed completely formed large mammae, 

 projecting fully seven inches from his chest with large and well formed 

 nipples. He had for several years served as wet nurse in the family of 

 his mistress. By applying a child to his breasts a supply of milk 

 could be developed at any time, if he should happen to be ." dry," and 

 the secretion once started was not easy to be arrested. Yet he was a 

 perfectly formed male. (Carpenter, 617.} The men of some of the 

 Pacific islands have large breasts precisely like those of the women, and 

 foreigners, judging by that mark, have sometimes mistaken them'for 

 women ; with amusing results. ( Austin. )

Velpeau states that cases of double 

 uteri are so frequent that new exam- 

 ples are met with every year. A sep- 

 tum or partition often occurs, starting 

 at the top and extending downward, 

 dividing the organ sometimes for only 

 a short part of its length, at other 

 times descending as low as the neck of 

 the uterus, completely dividing the or- 

 gan into two. A case is cited -by De 

 Graaf in which the separation includes 

 the vagina also, the development being 

 arrested at the stage of the Marsupial 

 type. Other cases of double vagina 

 are reported. There is also a case men- 

 tioned in which there is a short, com- 

 mon cavity, or "corpus," intervening 

 between the cornua of the uterus and 

 the vagina, the development being 

 that of certain Rodents.* The septum 

 in the uterus has sometimes an open- 

 ing in some part of it, allowing com- 

 munication between the two cavities, 

 showing an intermediate stage. The 

 septum in the vagina sometimes gives 

 it "the appearance of two united cylin- 

 drical canals, each having a hymen, as 

 occurred twice to Callisen and once to 

 Eisenman, or a single opening, as no- 

 ticed by Bartolin and HalleE, some-
