 about either in the muscle tissue or in the fascia above and are 

 not bound up into a compact mass; figure 3 (a section of a 225- 

 day testicular graft in female 6, AIBI-I) shows the dispersed 

 condition of the tubules imbedded in muscle. In figure 4 (same 

 age graft as in figure 3, but taken from female 6, AIBI-II) part
