Epididymis Testis - I/as deFerens Uterus masculinus Bladder — The kidneys, as already stated, are multilobulated, the lobules being small and numerous with a connective tissue packing between the sulci. On either side was a single ureter, each of which opened separately into the base of the bladder. I was unable to distinguish the sexes in the earlier stages by their external character, and it so happened that the four specimens which I dissected all turned out to be males. Whether this was simply bad fortune or whether it indicates that the number of males born preponderates over females I am uflable to say. The testes develop in relation to the kidney, and when recognisable as distinct organs, they lie at the posterior end of the kidney, there being a distinct depression in the latter in which the testis lies. The epidi- dymis lies along the postero-exter- nal border of the testis, the globus major and globus minor being dis- tinctly marked. The vas deferens leaves the hinder end of the epididymis and runs backward for a short distance and then bends sharply inwards towards the middle line. The two vasa enter the basal angles of an elongated hollow organ, which I think must be regarded as an unusually large uterus masculinus (see fig. above). Indeed, when I first saw this structure lying between the bladder and rectum I made sure that I was dealing with an ordinary female uterus. I found, however, that it opened into the neck of the bladder, and examination of the testis proved that my first opinion was incorrect. The sudden bend toward the middle line made by the vas deferens appears to be due to its being held in position by a delicate cord-like structure, which I at first took to be the round ligament of the uterus, but which can be no other than the gubernaculum testis passing forward from the inguinal canal. The descent of the testis appears to take place during the la
