Fie. 3. Seminiferous tubules from guinea pig testis (145-213) elevated to abdomen thirty days after birth, remaining in abdomen 4^ months, replaced in scrotum for five months. Complete recovery in this area, si, seminiferous tubule with spermatozoa; ta, tunica albuginea. stricting adhesions and the encapsulating fat. It was many times larger than when replaced in the scrotum and compared rather favorably in size with the normal testis opposite. From entire cross sections at three different levels one can see that the majority of the seminiferous tubules are in active spermato- genesis and a large percentage of these contain spermatozoa. Fig. 3 is a reproduction of a few normal seminiferous tubules,.
