STOKSTED* has been conducting experiments and investigations in the field of nasal physiology and contributes two articles dealing with nasal respiration. In the first one he presents the results in a series of tests for the determination of air resistance in the nasal chambers in 100 normal subjects. The measurements were made with a manograph, a sensitive manometer, the oscillations of which "are transferred to a calibrated roll of paper moving at a constant rate by means of an electric clock synchronizer." The manometer is connected to a nasal plug fitting snugly into one nostril, the subject breathing through the opposite free nostril. After a dozen or more respirations the plug is then transferred to the other nostril and the same procedure is carried out. Thus the pressure variations in the nasopharynx are transmitted through the tube connected with the closed nostril and recorded on
