Decrease in magnitude of contraction (height of twitch), and elongation (extension) of the curve, appear in either case as distinct- ive features. This is very apparent in the pulsations of the excised mammalian heart (55), when the fall of tem- perature (infra) plays an important part (Fig. 44). Although the condi- tion of muscular fatigue may thus be referred mainly to a preponder- ance of the D-process over the simultaneously occurring A-process, to a diminution of the store of decomposal >le matters, or of chemical tension, we must not neglect the other and important factor which KM:. 44.—Contractions of excised Kubbit'.s heart.
