Structure of the Regenerated Tail of the Gecko, 
A. Semi-diagrammatic transverse section of the regenerated tail of

lack of connexion with the cartilaginous tube (cr). FL= fat layer, 
The caudal artery and vein are seen underneath the cartilaginous

the longitudinal course of the latter (nat. size). C. Transverse 
section of the cartilaginous tube ( x cir. 150). Bv = blood-vessel ;
