The entire or- gan measures about one inch in breadth, and is composed of 12—20 tubules O'lo—0-2'" in diameter. The tubes which contain nothing but a clear fluid consist of fibrous membrane, lined by a single layer of pal_% cylindrical, epithe- lial cells. These tubular canals are not known to have any direct communication with the ovary. That the parovarium is formed out of the Wolffian body does not now appear to admit of doubt. It has been usually considered that the Wolffian bodies are organs peculiar to foetal life, and that they afterwards entirely disappear in both sexes. Hence no special investigations have been undertaken with a view to ascertain their ultimate fate. Meckel indeed compared them to the epididymis. Rathke believed that they became epididymis in the male, and disappeared in the female ; while Rosenmiiller, who discovered the paro- varium, compared this body to the epididy- mis. Some general conjectures also have pointed in the male sex to thevascu/a aberrantia of the epididymis, and in the female to the or- gan of Rosenmiiller and the ducts of Gartner, as the supposed remains of the Wolffian body. Nevertheless it is, according to Kobelt, an undoubted anatomical tact that each pretended ephemeral structure not only exists through the whole of life in both sexes, but that it absolutely increases up to its highest state of perfection, and first suffers a gradual re- trogression, alter the extinction of the repro- ductive function, but never entirely
