Goodwyn conceived that the heart ceased to act because the left side, being only arterio-contractile, was incapable of being stimulated by venous blood; but this idea was fully disproved by the experiments of Bichat, which render it certain that the blood stimulates the ventricles not by its quality, but by its bulk. (Goodwyn on the Connex. of Life with Resp. pp. 82, 83; and Bichat, Sur la Vie et la Mort.).
