As a microscopic illustration of the autotrausplant at twostages, Fig. 4 is given, a new example of the most frequentlyfound conditions in testis transplants. Even though the things explained in these illustrations arethe most frequently found, quite other conditions can be foundin some cases. Fig. 5 shows a microphotograph of a transplantfrom a rat, in which the Leydig cells were scarce, without theusual hypertrophy, while there were several unusually well de- 278 ENDOCRINOLOGY OF SEXUAL GLANDS 4 Fig. 4Guinea-pig No. 94.
