Fig. 9. Behaviour of three CBA skin grafts on three strain-A 

 Httermates. Appearance on day 33 after grafting. Mouse C 

 (treated at birth with CBA spleen cells + normal CBA serum) shows 

 partial tolerance (graft will be completely rejected on day 49); 

 notice absence of hair on most of the surface of the graft with 

 desquamation. Mouse T (untreated control) shows pigmented 

 remnants of graft rejected on day 10. Mouse C4-S(f) (treated 

 at birth with CBA spleen cells + facilitating CBA serum) shows 

 complete viability of the graft (observed up to the eighth month, at 

 which time it was killed).
