Fine1 and associates showed that bowel distention maintained for many hours causes marked concentration of the blood. They asserted that this cannot be explained by dehydration or by intraperitoneal loss of fluid. In their most recent publication they stated that they have been unable to account for it.2 (We have repeated many of their experiments with results the same as they reported.) In our other paper3 on this general subject we presented experimental and clinical findings which showed that the intraperitoneal loss of blood protein is considerable when the bowel is inflated by pressures which we believe act on the human bowel in cases of acute obstruction. We observed some local loss when we used the pressures which Fine employed. However, this loss is not sufficient in most cases to account for the great concentration of the blood which occurs after prolonged inflation of the intestine. Further,
