The swelling of the conchae can be seen in some cases by anterior rhinoscopic examination (fig. 1), but it can be clearly demonstrated in every case by means of a simple apparatus, the nasal plethysmometer (fig. 2).

The nasal plethysmometer2 consists of two small inflatable rubber balloons, A and B, each of which is mounted on one leg of a small manometer, C. When one of these balloons or both are introduced into the nose, one can blow them up without displacing the meniscuses, by means of the bridge, D, while the clip, E, is placed on the rubber connection, F. When the bridge is closed with the clip, E, on the rubber
