    Holzknecht refers to one peristaltic contraction, Kaestle, Rieder and Rosenthal to two peristaltic contractions, but there are many cases in which three or even four distinct peristaltic contractions can be demonstrated by this manner of examination. Figure IV demonstrates a one-and-a-half wave type of peristalsis which is intermediate between the one-wave type described by Holzknecht and the two-wave type described by Kaestle, Rieder and Rosenthal. Studying this case fluoro- scopically, one would observe only the one well-marked peris- taltic contraction and consider it as the type described by Holzknecht, but when studied radiographically there is clearly discernible a small secondary wave on the lesser curvature and Kaestle, Rieder and Rosenthal would claim it as a slight modification of their type of motor phenomena. Figure V shows one of these cases where four distinct peristaltic contractions are demonstrable. The radiograms, unfortunately, do not include the entire fundus, but the peristaltic contractions are seen on the greater and lesser curvatures, well up toward the fundus of the stomach. These contractions become deeper as they move pylorusward and in radiogram (C) Figure IV, we have the button-like contracted antrum, the formation of a pre-antrum, and two or possibly three antra yet to come. I think these plates particularly emphasize the point referred to by Kaestle, Rieder and Ros- enthal, namely, that it is unwise to preserve the term, “an- trum pylori,” and advisable instead to interpret what is seen in the region antrum pylori as an increase in the energy of the gastric peristalsis and as an accentuation in height and depth of the wave summits and depressions, only that tne well-marked contractions in this case are not limited to the pyloric region. I do not claim that this last case was normal, being aware that it was a case of hyperchlorhydria. The per- istaltic contraction is certainly more active than usual, bear- ing out the observations of Brauning regarding the relation between the tone of the stomach and its production of hydro- chloric acid.
