 Regeneration is determined by the level of amputation within the limb-field, and 

 not with reference to the organism as a whole. A, Dorsal, and B, Ventral, views 

 of a newt {Triton) in which the legs were amputated above the thigh, and shanks 

 were grafted in their place and subsequently amputated. C, Radiogram, showing 

 that only the tarsus and foot have been regenerated: i.e. structures distal to the 

 graft. (From Guyenot, Rev. Suisse de Zool. xxxiv, 1927.)
