    (Aus der internationalen Monatsschrift f. Anat. u. Phys. 1892. Bd. IX. Heft 7.) On the Electromotive Phenomena of the Mammalian Heartx) by W. M. Bayliss, B. A., (Oxon) B. Sc. (Lond.), and Ernest H. Starling1, M. D., (Lond.) M. R. C. P., Joint Lecturer on Physiology at Guy’s Hospital. (From the Physiological Laboratory of University College, London.) Expenses defrayed by a grant from the British Medical Association. (With pi. XV—XVII and 8 figs.) Although the electromotive phenomena of the heart of cold-blooded animals has been the object of much attention and investigation on the part of physiologists2), those of the mammalian heart have, till re¬ cently, remained uninvestigated. Waller and Weymouth Reid3) confined themselves to observations on the hearts of recently killed animals, and arrived at the conclusion that though, under certain conditions, the mammalian heart may show a diphasic variation indicating a wave of negativity starting at the base or apex, yet under normal circumstances it was probable that all parts of the ventricular muscle contracted simultaneously. This con¬ clusion they drew from the fact that in hearts examined immediately after death the variation was monophasic. The authors believe that their results justify the conclusion that the mammalian ventricle is not only controlled by nerves, but co-ordinated as to the action of its several parts, through intravascular nervous channels. a) This paper was communicated to the Royal Society on Oct. 23d 1891, and an abstract of it is published in the Proceedings.
