## Abstract A cyclic seasonal variation in forelimb regeneration in the newt, __Notophthalmus viridescens__, was noted under controlled environmental conditions at 20Β°C in previous experiments. Regeneration was enhanced in the summer months and reached its maximum linear growth rate in late springβ

## Abstract The forelimb of the newt, __Triturus (Notophthalamus) viridescens__, was bilaterally amputated and the animals subjected to different photoperiods during the period of regeneration, namely (1) continuous light, (2) 15 hours of light/day and (3) total darkness. Animals exposed to continu
## Abstract Newts with bilaterally amputated forelimbs were exposed to either continuous light (LL), total darkness (DD), or continuous light with the dorsal head epithelium painted with an India ink and Nile blue sulfate mixture (LLβIIβNBS) that limited light penetration through the skull to the p
