596 DR. J. MURIE ON A CASE OF MAI-FORMATION [UeC. 13, 



The structures forming this long urethra were an inner mucous lining, 

 surrounded by elastic fibrous tissue, but no true and continuous 

 corpus caveruosum or spongiosum. Nevertheless at the vaginal end 

 there was a space, of about an inch in extent, where the fibrous tissue 

 was in open network, the meshes closely resembling the peculiar 

 cellulovascular structure of erectile tissue belonging to the corpus 

 cavernosum and clitoris. 



As if further supporting the similitude of a penis, this urethral 

 canal possessed two long cord-like retractor muscles (R. m.) (erec- 

 tores clitoridis ?), which were closely applied to either side of its 

 outer walls. These muscles arose from the tissues between the tail 

 and rectum, and, running parallel with the tube, were inserted on 

 the right and left sides of the vulva. 



The vagina (V.) was considerably dilated, and measured 10| inches 

 from the os uteri to its abrupt termination in a cul de sac near the 

 rectum. This cut de sac was firmly attached by strong fibrous sub- 

 stance to the deep fascia of the perineum. The mucous membrane 

 and walls of the vagina were normal-looking and with the usual 

 numerous longitudinally parallel plications. On its inferior or ab- 

 dominal wall, 1£ iuch from the terminal blind sac, was a slit-shaped 

 opening, the meatus urinarius (m. it.), Posterior to this was a second 

 orifice, namely that which led into the long fibro-membranous tube 

 already spoken of, the common urino-genital canal. 



The uterus (U.) and appendages, as a whole, appeared completely 

 developed, and the former of regular dimensions. Each cornu, as 

 well as the body and neck of the uterus, when cut open also showed 

 nothing abnormal ; the former had small cotyledonal elevations, the 

 latter the usual longitudinal and transverse rugae. The os tincce 

 (o. t.) was well formed. The dimensions of the uterus were as fol- 

 lows : — From the os tiucae to the divarication of the cornua 2" - 7, 

 each cornua (following the curve) about 7 inches in length. 



The ovaries, right and left (o. o'.), were contained in the folds of 

 the broad ligament ; but neither of these bodies were of large size. 

 A section of the right one disclosed two corpora lutea, of a reddish 

 colour and of a dense homogeneous texture. The larger one of these 

 corpora lutea equalled a canary-seed in size, and projected slightly 

 upon the surface of the ovary. 



The Fallopian tubes terminated in delicate but well-formed fim- 

 briated extremities (/■/'•), but were not pervious for their entire 

 length. This was ascertained by first trying to pass a very delicate 

 silver wire along the canal from the end next the uterus, but which 

 would not enter beyond a third of the way. Afterwards a thin- 

 coloured injection was forced in from the opening at the fimbriated 

 extremity ; but this ran in only as far as a third of the distance from 

 that side, while a fluid introduced from the cornual or uterine end 

 did not pass any further than the wire — thus proving that the middle 

 third of the tube was in a closed condition. 



The urinary bladder (JJ. b.) had its usual relative position with 

 respect to the uterus and other viscera. In its contracted state it 

 measured from the fundus to the neck about 7 inches. The neck («.),
