Information more exact, though possibly open to error, may be obtained by the use of more elaborate apparatus, and the graphic method. Fig. 216 gives an idea of the main features of th9 pulse-trac- ings of an arterial scheme or arrangement of tubes in supposed imitation of the conditions existing in ^e vascular system of the mammalian body. Attention is especially directed to the abrupt ascent, the more gradual descent, uid the secondary waves, which are either waves of oscillation or reflex waves. It may also b
