This study in the human heart is complicated somewhat by the fact that the sinus region is not so well separated from the auricle or atrium as it is in the lower animals, on which much of the experimental work has been done. An interesting observation has recently been made by W. Koch.1 This observer had the opportunity of examining the dying heart of a human fetus and of comparing the phenomena there with the dying process in the rabbit's heart.
