598 DR. J. MURIE ON A CASE OF MALFORMATION [Dec. 13, 



culse seminales coexist, but, according to Hunter, no vasa defe- 

 rentia*. 



Prof. Simpson f has placed this case of Hunter's "Free Martin" 

 under his division of " Transverse hermaphroditism with the external 

 organs of the female type," while M. Isidore Geoffroy Saint-Hilaire J 

 has regarded it as belonging to his " Hermaphrodismes neutres." 



Without deciding which of these two authors' views is the more 

 applicable one, it is sufficient for my purpose to remark that the 

 fact of the creatures possessing testicles and vesiculse seminales, and 

 only a very doubtful and imperfectly pronounced uterus, with natu- 

 rally formed outward female genital organs, completely differentiates 

 it from our Porto Rico animal. 



In the second Hunterian specimen, now forming no. 242 in the 

 above ' Catalogue ' of the College, it appears that the animal had an 

 Ox-like aspect, with the outward genital conformation of a Cow, the 

 vulva being placed lower down than usual, but not so entirely abdo- 

 minal as in the animal forwarded by Mr. Latimer. From exami- 

 nation of the Museum preparation, the distance between the anus 

 and vaginal aperture is nearly as much as 12 inches, in this respect 

 bearing resemblance to our case ; but the perineal raphe is by no 

 means so well marked. 



The vulva also, and the clitoris in its peaked prominent form, more 

 nearly agree with what is the normal condition in Cows ; but, as in 

 the Society's specimen, there are long and projecting hairs at the 

 genital outlet. The uterus, however, is very defective in structure. 

 Testicles are present, and a true penis. This latter occupies its 

 usual abdominal situation as in Bulls ; but it is of small calibre, di- 

 stinct, and tortuous, although not perfectly developed, so far as an 

 outer passage is concerned. 



The presence of a male abdominal organ approximates it to our 

 specimen; but the line of demarcation is clear; for, besides this small 

 organ, there is a natural vagina, along with other true male structures 

 wanting in that which I have described. 



The two instances cited above, taken along with that forming the 

 subject of the present paper, afford remarkably good illustrations of 

 abnormalities wherein the type of sexuality sways from male organs 

 internally and female externally to very nearly female organs inter- 

 nally and male externally, which curious anomaly has its antecedents 

 in the evolution of the organism in utero. 



In reasoning as to the probable origin of hermaphroditism, most 



* Gurlt, as quoted by Simpson (foe. cit. p. 702), expresses an opinion that the 

 deferent vessels are what Hunter has mistaken for the uterine horns. The pre- 

 sent bottled condition of the specimen renders it difficult to redetermine this 

 point.

% Histoire des Anomalies, tome i. p, 289. In comparing as above the Society's 

 animal with Simpson's classification (a modification of Gurlt's), rather than adopt- 

 ing the celebrated French anatomist's divisions, I have been guided solely by the 

 facility of its comprehension, preferring not to enter into a discussion regarding 

 the significance of the term neuter as applied by Geoffroy to cases exhibiting 

 doubtful sex.
