Little attention has been directed to the action of the nares as a possible cause for the altered physiology of the nose and as a factor in producing secondary sinusitis, with its aftermath. Physiologists have placed little stress on the importance of the nares as an obstruction in the deviation of air currents. This has been brought to light by Proetz in his experimental work on animals.
The results of Proetz'1 experiments with smoke demonstrated that the direction of air currents is determined by the shape and position of the nostril and the angle at which the inspired air impinges on the slope of the bridge of the nose. It also appeared that employing a head with thin and shrunken middle turbinates or one with an amputated middle turbinate did not materially alter either the inspiratory or the expiratory air currents. Introducing obstacles of any description on either the septal
