Abstract
Dishoeck (1935) confirmed the claim for the discovery of nose “opening” rays made by L. Hill (1932), a discovery denied by Dufton and Bedford (1933) and Winslow, Greenburg and Herrington (1934). By means of a blower fan and a well-fitting tube Dishoeck sends a stream of air through one nasal orifice and out through the mouth while the subject holds his breath. The input pressure of the air, meanwhile, is measured by a water manometer which is connected with the air tube just before this enters the nasal orifice. A few seconds suffices to secure such a reading. He calibrates the instrument by measurements made with glass tubes, each about the length of the nasal passage, viz. 6 cm., and fitted with varying diaphragmatic holes.
