The interstitialcells were well developed like in the testis of the normal controlanimal (fig. 5). Dr. Wagner found even several mitoses, aphenomenon very rare for interstitial cells. The microscopicalexamination of the right testis gave somewhat similar results. This observation leaves no doubt that full development of asexual character which depends upon the internal secretion ofthe testis, is possible Avithout any spermatozoon having to the question Avhether other stages of spermatogenesis arenecessary for the entrance of the testicle into puberal hormonicactivity, this observation gives no definite information, as it was. ^m Fig. 3.
