To the physiology of nasal breathing

Abstract

I give the results of observations of my own breathing, with the proviso that my nose is perfectly normal, and I rarely suffer from a runny nose. In the tables below, d indicates that the main stream of air at a given time went through a given half of the nose, while the other was either completely blocked or breathed through it with difficulty; p indicates that at this moment the breathing through both nostrils was approximately of equal force; ^r/_p indicates that breathing was through both nostrils, the left nostril breathing harder. The results were noted at ½ hour intervals.
