Abstract

In a recent paper experiments were cited which indicate that developing sea-urchin eggs when subjected to suitable concentrations of various liquid-soluble substances, i.e., the higher alcohols, show unmistakable rhythms of susceptibility and resistance according to the phase of physiological activity at the specific time of treatment. Such observations constitute additional evidence that a very intimate relation or correlation exists between the general physiological condition of the egg, and the physical state of its plasma-membrane. The present paper is a preliminary report of experiments conducted in the light of recent advances to analyze the effects of various concentrations of the alcohols upon the resulting fatigue curves of excised frog muscles so immersed. The bearing such a study has on the theoretical and practical aspects of responses is apparent when one recalls that in any protoplasmic system, an increased (sensitization) or decreased irritability or spontaneous activity (anaesthesia) may be brought about by the conditions of concentration, temperature, and the physiological state of the system.
