In this monograph on the physiology of the stomach, the author presents a series of hypotheses on the function of the stomach. The book is divided into four parts. The first chapter deals with the fundamental laws governing tone and peristalsis. The author enumerates them as follows:
Tone is independent of peristalsis. Peristalsis, however, is a function of tone.
Peristalsis has a stimulus threshold.
The stimulus threshold of peristalsis is dependent on the degree of tone and the increase of pressure.
The second chapter is devoted entirely to tone; the third, to peristalsis and the fourth, to emptying.
The hypotheses are proved by animal experimentation as well as clinical roentgenologic studies. The author makes good use of roentgen kymography. The monograph includes a neat device which enables the reader to restore motion to the kymographic illustrations.
In the preface Dr. Weltz expresses the hope that he will
