    shows the disappearance of this intervening tissue, and the fusion of these two structures with one another, even to the junction of the accompanying vessels. In minutely investigating the pedicle, the infolded character (previously referred to) of one surface is very well shown (fig. 6), but the most noticeable feature is the large artery and vein in its midst, and disposed around these are some very scattered and partially obliterated tubules, with a very sparse coating of involuntary muscle, which I consider to be the remains of the continuation of the collecting tube, or rather Fig. 6.—Section of hydatiil stalk (from female) near its point of emergence from> broad ligament. 1, peripheral fibro-mnseular layer ; 2, atrophied tubules ; 3, large central vessels ; 4, broad ligament (adjacent). Wolffian duct proper, into the pedicle. These tubules, more- over, are dotted about in a groundwork of fibrous connective tissue. As one examines more and more distal sections (ic., nearer the cyst) their number decreases, and the more evident their degeneracy appears, until they, to all intents and purposes, vanish. A more remarkable feature is the continued large size of the artery and vein. Surrounding these vestigial structures is a curious layer extending right round the periphery, and composed of involuntary muscle fibres, with a large admixture of somewhat dense fibrous tissue. The surface of the pedicle has an endothelial lining.
