These tubules lie near theaorta; their glomeruli develop to the right and left of the mesentery(Fig. 77). Mesonephros.—The pronephros is retained in certain fishes. In 168 MESONEPHROS. amphibise it disappears; in amniotse evidences have been found. Re-mains have been described in rabbits, and evidences of its existence areclaimed to persist in man, and it is probable that it develops in thesame manner as in mammals.

(0. Schultze.) Shortly after the formation of the pronephros, in animals in whichits existence is only rudimentary, there develops the mesonephros, orWolffian body. It originates immediately posterior to the pronephros onthe following section of the Wolffian duct. Medial to the pronephros,between the middle plate and the primary vertebras, the blastoma ofthe Wolffian body appears. AortaPrimary kidneyor mesonephrosIntestine Art. u nihil icul is —
