FIG. 7. Number of fibers in the nerve to the triceps femoris of embryos of
Eleutherodactylus
plotted against volume of muscle. For hypophysectomized embryos, the number of days between operation and fixation is given. The thyroidectomized embryos were fixed 7 days after operation. (From Hughes, 1966c.)
