The laws and mechanics of circulation, with the principle involved in animal movement . g it instantaneously. And yet it is to count for nothing.

A pretty let gothat is. Fie on it! Nature works by law ; your theory doesnot, and you must bring it into correspondence, else stay inouter darkness. You offer no reason for it, whereas there is areason for everything that Nature does. It is a true saying: One lie is the father of many. But Truth is a sleuth-hound—terrible, and the progeny is doomed. This action of the nerves upon the vessels has forcible illus-tration in the case of the vessels and nerves to the salivaryglands, notably the submaxillary and sublingual glands (). Thus, when the chorda tympani (c) is irritated, the T.
