Pumps maydiffer, but the principle never changes, and this it would be wellto bear in mind—not to be lost sight of for a single moment, else AUTOMATISM IN THE VESSELS DEMONSTRATED. 141 all is chaos in this mechanics. Well, the result of the threetracings thus produced is to be seen in the three undulatinglines (Fig. 44, 1, 2, 3). In the lowest tracing—the one near-est the bulb of the syringe (I)—the undulations are greatest,while in the uppermost tracing (s) they are smallest and upon. Pig. 43.—Marey. the point of extinction. Now, then, where is the correspond-ence spoken of as subsisting between the tracings producedby this artificial scheme and the tracings which are producedby the action in the arteries % For the life of me, I cannotperceive where it comes in. No, not at any place whatevercan it be seen in any one of these tracings. For example,
