## ONE FIQURE If the blanching and the darkening of such a fish as Fundulus are due to the action on its melanophores of a concentrating neurohumor from its concentrating nerve fibers and of a dispersing one from the opposing fibers, it might be possible by appropriate stimulation to exhaust one o

No humoral substance has excited in the vertebrate melanophore such constancy of respoiise as adrenalin. All reactive integumentary melanophores in vertebrates concentrate their pigment to adrenalin and all reactive retiiial melanophores in these animals disperse their pigment to this hum0r.l Notwit
## T W O FIGURES Which is the active and which the resting state of melanophores is a question that has been a matter of speculation for over a century. The majority of workers on this subject have declared in favor of the view that melanophores with concentrated pigment are in an active state an
## THXRTEEN FIGURES Changes in dispersion o r concentration of pigment within melanophores of vertebrates have been studied chiefly by the use of tlie microscope, and as a scale of measurement the melanophore index of Slome and Hogben ('28) has been adopted widely. This system has the disadvantage
