Itudolphi has referred to a second and more ancient example of lateral hermaphroditism in the hen, mentioned by lleide.t The case, en titled by the author " galli qui putabatur her maphroditus anatome rudis,' is so imperfectly detailed as not to be entitled to much attention.
We have ourselves been fortunate enough to meet with two domestic fowls that presented in their sexual organization examples of lateral her maphroditism. In the first of these cases (fig. 290) the female sexual organs were placed on the p. 645; left side of the body, and the ovary (a) and ovi- pp 72. duct (b) were in all respects apparently rally formed. On the right side, a male vas P. deferens (d), of about half the normal length, ran up from the cloaca to opposite the origin of the iliac vessels (c), and during this part of its course was bent into those short transverse zig zag folds which characterise the structure of this part in the common cock. (See article AvEs, vol. i. p. 354.) When it reached the middle third of the kidney (d d), it lost this particular form, became membranous ( e), and after pro ceeding upwards for about an inch, in the com mon course of the canal, at last disappeared. The convoluted or contorted portion ran over a space of about two and a half inches, and if unrolled would have extended three or four times that length. Its canal was about the usual size of the same part in the perfect cock, and perhaps at some parts even more dilated. Its cavity was filled with a whitish seminal-looking albuminous fluid, which at first prevented a mercurial injection from readily passing through it. There was not any appa rent vestige of a testicle. The fowl that was the subject of this malformation possessed in an imperfect degree the plumage, comb, spurs, and general appearance of the cock, and when young was considered to be a male until the time it commenced to lay eggs, which it did very constantly, except during the moulting season, up to the time of its death. Its eggs were remarked to be very large. They bad re peatedly been tried to be hatched, but always without success. The bird itself was never known to incubate. It was peculiar in its habits in so far that in the barn-yard it did not associate with the other poultry, and at night roosted sepa rately from them. It crowed regularly, espe
cially in the morning, and often attempted copu lation with the hens.
In the second case, the ovaries and oviduct on the left side of the body were, as in the former example, natural in themselves; but in the mesometry of the oviduct, a tube of the size of the male vas deferens was found. This tube, like the normal vas deferens, was thrown into the distinctive angular folds. It ran for about an inch and a half through the upper portion of the mesometry, was blind at either extremity, and admitted of being injected with quicksilver. On the right side, there was also a male vas deferens, marked with the characte ristic angular folds. The contorted portion of this canal only stretched in this instance to about an inch above the cloaca; but the folds were even stronger than in the first case, and the tube itself was rather more dilated. Above or anterior to this convoluted part, the tube be came straight and membraneous, and ran up in this form for about two inches in its usual track over the abdominal surface of the kidney ; but there was not at its upper extremity any trace of a testicle. This bird presented during life, in a very slight degree only, the appearance of a cock, its comb and spurs being even less developed than in the previous case. It skewed the same solitary habits in the poultry-yard. It layed eggs regularly. On three different occa sions I liad a number of them submitted to incubation, but in none of them was a chick produced.
In the Quadruped, Schlump* has mentioned an instance of lateral hermaphroditic malfor mation. In a young calf he found on the left side, under the kidney, a small testicle having attached to it a vas deferens, which was con nected with the peritonmum towards the abdo minal ring of the same side, and there became lost in the cellular texture of the part. An ovary and Fallopian tube, with an uterus consisting of a single horn only, were connected to the right side of the loins by a ligament. The neck of the uterus lost itself in the cellular substance beneath the rectum, and there was no vagina. The external organs were male, but imperfectly formed. The udder occupied the place of the scrotum.
