X Observations Concerning Movement of the Heart, the Auricles and Vena Cava, Extracted from Dissections of Various Animals Carried out Here and There

Abstract

1. In a cat, as the peristaltic movement of the intestines and many and big swellings of the biliary vessels had retained us in their examination for a long time, returning to the heart, we found everything immobile. But hardly had I compressed it three or four times with my fingers, their movement returned immediately to the heart and to the vena cava, although very rare, but together and very distinct, so that, as it appeared clearly, the movement started in the vena cava, now from its upper part, then from its lower part, and ended near the heart.
