The right hemispheres of the cerebrum and cerebellum, particularly that of the latter, were smaller and less developed than the left, and the left side of the occiput was externally more prominent than the right. lie is stated by Professor Mayer to have shewn a certain predi lection for females, without, however, feeling any sexual desire.
2. Testicle on the left, and ovary on the right side.—An instance of malformation of the reproductive organs minutely described by Maret,* and which is in all its more essential anatomical points an example of lateral herma phroditism, may be included under this head.
a. The subject of the case (Ilubert Jean Pierre) died in the hospital at Dijon in 1767, at the age of seventeen. On the left side a perfect testicle was discovered with its usual spermatic vessels, vas deferens, and vesicula seminalis, all occupying the natural situation in which they are placed in the male adult. The vesicula scminalis contained a fluid of the colour and consistence of semen. On the right side an oblong cystic tumour was found lying in the iliac fossa, and stretching outwards into the inguinal region. On opening it a quantity of reddish limpid fluid escaped, and then the solid contents of the tumour were seen to consist of a somewhat flattened body, that gave off from the upper part from its right side a short Fallopian tube; and at the fimbriated extremity of this tube an ovary of the natural size, consistence, and figure, was situated. The roundish shaped body to which the tube was attached was about an inch and a half in its greatest, and an inch in its smallest diameter. It contained in its centre a small cavity continuous with that of the tube,—a circumstance, which, along with the structure of its walls, left little doubt that the body itself was an imperfectly formed uterus. No other opening except that of the tube could be traced into its cavity. Its external surface was attached to the ovary by a kind of ligament. On this same side of the body (the right) there existed also a vesicula seminalis, but smaller and more shrivelled than that on the left. It gave off a vas deferens, which became gradu ally smaller as it was traced backwards, and at last disappeared altogether without being con nected with any structure resembling a testi cle. In regard to the external organs of
generation, the penis was four inches long and imperforate, but in all other respects per fectly formed. It possessed a corpus spongi osum, which does not exist in the female clitoris. On raising the penis, it was observed to cover a large fissure, the sides of which resembled the labia of a female. In the left labium or left half of the scrotum the testicle already alluded to was placed, but there was none in the right. When the labia were separated, two red spongy bodies were seen, resembling the nymphs` in appearance, and seemingly consisting of the sides of the split urethra. Between these bodies and at their upper part, the urethra opened as in the female ; while below there was a very narrow aperture covered by a semilunar membrane, and pre senting on one side of its entrance a small ex crescence somewhat resembling in figure a caruncula myrtiformis. This orifice led into a membranous canal or cul-de-sac an inch in depth, and half an inch in diameter. On the lower part of this canal the verinnontaniim and orifices of the seminal ducts of both sides were discovered.
During life Pierre had been considered a male, but was not known to have shown any partiality for the female sex. His counte nance was more delicate than what we ordi narily see in the male sex. There was no beard on the face ; the larynx was not enlarged as in man ; and the mamma:, each of which was furnished with a very large areola, were of a moderate size and roundish form. The con figuration of the lower part of the body was more decidedly masculine, and there was none of that enlargement of the buttocks and projection of the thighs, from the increased width of the pelvis, which is observable in young females.
In this case we have on the left side of the body male sexual organs, consisting of a per fect testicle, vas deferens,and vesieula seminalis. On the right side, again, we have a female ovary and Fallopian tube with a rudimentary uterus, together with an imperfect male vesicula semi nails and vas deferens.
