Abstract

It is hard for a moment to realize that our knowledge as regards gastric physiology is today in much the same stage as it was as regards cardiac physiology back in the early seventies, before the sequence of the beat in sinus, auricles and ventricles had been studied by means of graphic records. In those days the research workers simply watched the slowly beating hearts of dying amphibians and tried to understand the movements which they saw, much as we, today, try to understand the sequence of the gastric waves as they appear before us on the fluorescent screen. To be sure, we obtain graphic records by taking plates, but such plates are snap shots which cannot help the physiologist very much. A few roentgenologists, notably Rieder in Europe and Cole in America, have secured interesting serial roentgenograms of the stomach; but the technic has been so difficult and the
