We have met with a free-martin cow, in which upon dissection we found an arrange ment of sexual parts very similar to that described in the preceding case. The uterus, however, though small, was pervious for a distance of some inches above the vagina ; and at the abdominal end of each blind Fal lopian tube there was a dilated sac of con siderable size lined by peritonaeurn, and open ing into the abdominal cavity by a small orifice. These sacs we considered as abortive attempts at the formation of the fimbriated extremities. The imperfect bodies which we considered as testicles were placed near the cavities which we mention, in the situation of the ovaries. They were small in size, and of an oblong shape. On a section being made of them, they sheaved internally a kind of dense ho mogeneous yellow tissue, dotted or crossed with strongly marked white lines. The vasa deferentia could be traced along each side of the uterus in the form of broken dense cords. The vesicular seminales were large and partially hollow, and near them on each side there was an oblong body of considerable size, having the appearance of Cowper's glands. The tubes from them, and from the vesicular scminales, opened near the os tincw into a vagina of nearly the usual size.

—In the cases included under this second division of double hermaphroditism there exist a male testicle, or testicles, visa deferentia, and vesicular seminales, along with a female uterus. The uterus occupies its normal situ ation between the bladder and rectum. It is sometimes defectively developed, and of a membrannus structure; and occasionally it is not provided with Fallopian tubes, or, in the quadruped, with cornua. The cavity of the uterus communicates with a vagina that either opens in its usual situation externally, or, as happens more frequently, joins the male ure thra. In some cases the vaAitia is wanting, and the uterus opens directly into the canal of the urethra.
Several cases of sexual malformation in the ram, goat, and dog referable to this variety of double hermaphroditism have been described by different authors; and various analogous instances have now also been observed in the human subject.
In a lamb described and delineated by Mr. Thomas,* all the external parts were male, but the scrotum was divided or hypospadic. In ternally there were two perfect male testicles in the situation of the ovaries, with their epidi dymes, vasa defcrentia, and vesicular seminales ; and a well-formed two-horned uterus furnished with its usual ligaments, and with Fallopian tubes that ran up and terminated in a tortuous convoluted manner upon the testicles. The body of the uterus possessed the common rugose structure, hut the horns were lined by a smooth membrane without their usual glandular bodies internally. At the anterior extremity of the fundus uteri, a thick semilunar valve, which seemed to correspond to the os tincw, passed across and hardly allowed a fine probe to be entered over its upper edge. The vagina
scarcely existed, and formed only a short smooth pouch terminating below in a cul-de sac. The male vesicular seminales and vasa deferentia entered the male urethra in their normal situation at the eaput gallinaginis.
Gurltt has described and delineated the sexual parts of a goat in which all the inter nal male genital organs, with the exception of Cowper's glands, were found (fig. 300). There was also present an uterus (c) provided with long but narrow and curved cornua (If), that accompanied the vasa deferentia and tes ticles through the abdominal rings, and ended blind at the epididymes. The testicles lay externally upon the udder, which was of con siderable size. The scrotum was absent; the penis (g) was short, tortuous, and imperforate ; and there was a fissure in the perinieum into which the urethra (h) opened.
Stellatit has recorded an analogous case in the same animal. The male sexual organs were not entirely complete, and there were superadded to them a female vagina and an imperfectly developed uterus, the Fallopian tubes of which ran towards the inguinal rings, and terminated with them upon the epididymes of the testicles.
Another instance of hermaphroditic malfor mation in the goat, detailed at great length by Heckel,* seems also in its principal points justly referable to the present division of cases, although there was at the same time a tendency, in the unequal size of the two coma uteri, &c., to a degree of lateral hermaphroditism. Professor Mayer, of Bonnif has detailed at length the dissection of three hermaphroditic goats, in all of which the conformation of the sexual parts resembled in its more essential parts the preceding cases of Thomas and Curb. In all the three instances there were found two male testicles with their epididymes, vasa de ferentia, and vesicular seininales ; and at the same time there was present a well-marked female two-horned uterus, with a vagina open ing into the urethra. In the first case the large hollow cornea uteri terminated in blind ex tremities, and there were only very short im pervious rudiments of the Fallopian tubes. In the second case, at the extremity of the right horn of the uterus, a blind appendicula was situated, formed by a vestige (according to Mayer) of the Fallopian tube ; and from this a ligament was sent off to the correspond ing testicle ; a similar ligament, but no appen dieula, existed on the left side. In the third case both Fallopian tubes were present, and each ended in a bursa formed by the lamina of the peritoneum, and partly surrounding the testicle and epididymes. In two of the in stances the ejaculatory ducts seem to have opened into the urethra near the point at which the vagina terminated in it ; and in one of the cases they opened into the canal of the vagina itself before it joined that of the urethra. All the external organs were male, but malformed in so far that the penis was short, and in two of the cases somewhat twisted ; and the scrotum was either small or wanting.
