IVeberian Organ of the Deer, a, a, vasa defurentia; b, b, se- minal vesicles; c, Weberian organ. a, a, Weberian Organ of the Goat. seminal ducts; b, b, seminal vesicles; c, Weberian organ. in the majority of he-goats a less complete found. But in the bullock I found immediately development of the Weberian organ occurs. According to my observations the ore;an under the orifice of the vasa deferentia a small and scarcely noticeable roundish aperture, consists of a cylindrical body, which ascends through which a probe penetrated about two between the two seminal ducts, and is strongly lines in depth, evidently into the tubular united to these by areolar tissue, especially cavity of a small Weberian organ, which was in its interior half. After a course of an inch covered by the heart-shaped mass of the pro- and a half it splits into two horns, which are state apposcd to the seminal ducts, and continue with these to the testicles, where they pass into the covering of the epididymis. In two instances the lower third of the body was dilated into a longish vesicle of about three lines in diameter, while the part above this measured scarcely one line. At the seat of bifurcation it was again dilated, though less considerably. In one individual the middle portion was obliterated so as to form a solid cord. The point of opening into the uro-genital canal is a small linear fold, which is separated by a short interval from the orifices of the vasa deferentia, and is usually placed below, but, in one instance, above them. The genitals examined were those of either new-born individuals, or of such as were but a few weeks old. In two instances, which were in no way distinguished by a special development of the Weberian organ, the uro- genital canal was wider and shorter than normal, measuring from 2 to 2i inches long onlv, instead of about 4 inches, while the penis was smaller, and twisted into numerous zigzags or spirals. But in other respects the male organs were quite perfectly developed; the urethra opened at the extremity of the penis, and the testicles had descended into the scrotum. In the sheep there is no Weberian organ. Even in the new-born individual, neither its opening nor any other indication of it can be Fig. 881.
