Abstract
THE immersion of frog muscle in Ringer solution, with a high potassium content, is known to cause a decrease in the resting potential of the fibres accompanied by a large increase in oxygen consumption and heat production of long duration; no mechanical change of muscle is observed in these conditions. A possible cause of this effect was discussed by Hill and Howarth1, and a hypothesis was suggested according to which the depolarization produced by potassium releases the catabolic processes normally accompanying contraction of muscle. Nevertheless, the whole mechanism is still very obscure.
