In 1829, an account of an hermaphroditic goat was published at Naples, which is said to have been provided with both female ovaries and male testielcs4 The two ovaries occupied their usual situation ; no Fallopian tubes were found ; but there were present a double-horned uterus with blind cornua, and a vagina which opened externally, as in the female. In the neighbourhood of the ovaries, and more ex ternal than them, two small testicles were dis covered, having two vasa deferentia arising from them. The vasa deferentia ran down wards to two corresponding vesicular seminales, that were placed alongside of the uterus. In the lower angle of the external pudenda, a body, resembling in length the male penis more than the female clitoris, was situated : it was, as we have already had frequently occasion to mention in regard to the penis in malformed male quadrupeds, of a very tortuous or con voluted form.
We have had an opportunity of examining an excellent preserved specimen of double herma phroditism in the sow, referable to the present section, which was met with some years ago by Dr. Knox, and we have his permission to state here the following particulars of the case.
Among the internal female organs there is present a natural well-formed double uterus, provided with broad ligaments and two hollow cornua, each about six or seven inches in length. The fimbriated extremities are not distinctly marked, the female tubes appearing to end blind at their upper terminations, as they have often been observed to du in similar cases. The os uteri opens inferiorly into a vagina, which seems normal in its structure. At a short distance from the upper extremity of each horn of the uterus, two bodies of considerable magnitude are seen lying in close juxtaposition. The smaller of these two bodies is on either side about the size and shape of a large almond ; and though internally of an indeterminate amorphous structure, they are considered by Dr. Knox as answering to the two ovaries. The two larger bodies, which are placed between the supposed ovaries and the upper extremities of the corium uteri, are most dis tinctly testicles, as shewn by their numerous tor tuous seminiferous tubes, which have been suc cessfully filled with a mercurial injection. They are of the full size of the organ in the adult male. The seminiferous tubes of each testicle terminate in a vas deferens, which was injected from them ; and the two vasa deferentia run downwards through the ligaments lata of the uterus, and terminate inferiorly in the upper part of the vagina, thus following the course of those natural canals in the female sow that we shall afterwards have occasion to allude to at greater length under the name of Gaertner's ducts, and which Dr Knox, from the evidence of the present atse, believes to be in reality typical of the male vasa deferentia. There is no trace of vesicular seminales. Externally the vagina opened along with the urethra upon the perinamin, at a point lower than natural in the well-formed female. The clitoris in situa tion and size was nearly normal.
The animal at the time of death was fourteen months old ; it was ferocious in its habits ; and it had been in vain tried to be fattened. It had repeatedly shewn strong male propensities, and at the season of heat its vagina is said to have presented the usual injected appearance ob served in the female sow.
Dr. Harlan of Philadelphia* has lately described a still more perfect instance of dou ble hermaphroditism than any of the precedin,, which he met with in the body of a gibbon or orang outang, from the Island of Borneo (Simla coneolor). This animal died of tuber
cular disease in Philadelphia in 1826, when it was considered to be under two years of age. Dr. IIarlan gives the following account of its sexual formation. The penis (fig.304, a) was about one inch in length, and subject to erec tions ; it terminated in an imperforate glans ; and a deep groove on its inferior surface served as a rudimentary urethra. This groove extended about two-thirds of the length of the penis, the remaining portion being covered with a thin articular diaphanous membrane, which extended also across the vulva (b), and closed the external orifice of the vagina. The vagina was rather large, and displayed transverse strim. Traces of the nymphs: and labia externa were visible. The meatus urinarius opened beneath the pubis into the vagina, but the urine must have been directed along the groove of the penis by the (fig. 304, c) was divided, and consisted of a sac on each side of the labia externs, at the base of the penis, covered with hair. The testicles (fig. 304, d d) lay beneath the skin of the groin about two inches from the symphysis pubis, obliquely outwards and upwards: they appeared to be perfectly formed with the epi didymis( jf), &c. The most accurate examina tion could not discover vesicula seminales; but an opening into the vagina, above the meatus urinarius, appeared to be the orifice of the vas deferens. In all other respects the male and female organs of generation were in this animal as completely perfected as could have been anticipated in so young an individual, and resembled those of other individuals of a similar age.
Two imperfect instances are on record of the co-existence of male testicles and female ovaries in the human subject.
a. The first of these cases is detailed by Schrell.* It occurred in an infant who died when nine months old. All the internal and external male organs were present and perfectly formed, with the exception of the prepuce of the penis, which seemed divided in front and rolled up. At the root of the large penis, was a small vulva or aperture capable of admitting a pea, and provided with bodies having an appearance of labia and nymphs:. This vulva led into a vagina that penetrated through the symphysis pubis, and terminated in a nipple-like body or imperfect uterus, to which, structures having a resemblance to the Fallopian tubes and ovaries were attached.
b. The other and still more doubtful case of the alleged existence of both testicles and ovaries in the human subject, was first pub lished by Beclard.-l- The case was met with by M. Laumonier of Rouen, who injected and dissected the sexual parts, and deposited them in a dried state, along with a wax model repre senting them in their more recent condition, in the Museum of the School of Medicine at Paris. In the wax model two female ovaries with an uterus, vagina, external vulva, and large imperforate clitoris, are seen combined with two male testicles, the vasa deferentia of which terminate in the uterus at the place at which the round ligaments are normally situ ated ; these ligaments themselves are wanting. The preparation of the dried sexual parts is far from being equally satisfactory, and, in its present imperfect condition at least, does not bear out by any means the complete double her maphroditic structure delineated in the model.
