    SOME OBSERVATIONS ON THE ORIGIN AND NATURE OF THE SO-CALLED HYDATIDS OF MORGAGNI FOUND IN MEN AND WOMEN, WITH ESPECIAL REFERENCE TO THE FATE OF THE MULLERIAN DUCT IN THE EPIDIDYMIS. By John H. Watson, M.R.C.S., late Holt Fellow, University College, Liverpool; Assistant Demonstrator of Anatomy, Tjondon Hospital. In this commuiiicatioii I intend to consider the fate of the Mullerian duct in man first, since not only can one trace it definitely with the aid of the microscope, but by eliminating the fcetal residues likely to remain in connection with it, one is able to study with less chance of confusion the more com- plicated vestigial structures that are linked together with the Wolffian duct. Most anatomical text-books state that tacked on to the testicle are two hydatid bodies, one having a pedicle, the other fjeing without; and the sessile body is described as a derivative of the Mullerian duct. Now, in order to corroborate this last statement, I have made a considerable number of microscopical sections of testicles with the epididymis attached, the results of which are here stated as briefly as possible; and although very little, if anything, new has been made out, the work is interesting I think, in that it confirms the observations pub- lished by Loewe and Roth on the continent some time ago. The Aessilc Hydatid of the Testicle. Before entering into the microscopical details, it will be worth while to note the macroscopical peculiarities of the sessile hydatid. After examining a large number of testicles, my own experience is that the sessile hydatid is much more frequently present than the pedunculated one ; moreover, instead of being transparent and bladder-like, as its name implies, one
