If we keep in mind,that the tendency of the stream of inhaled liquid, is to takethe same direction that the air does, and that the water, be-cause it is heavier than the air, will deviate from this courseby gravitation, we have only to place the head in certainpositions, to be enabled to wash or bathe the entire surface ofthese triangular shaped cavities, except the inferior ]X>rtionsof the turbinated processes. To reach the anterior third of the nasal cavities, the headof the patient should be inclined forward to such an extent,that the plane of the forehead will be nearly in a horizontal CLEANSING THE N AS SAL PASSAGES. 387 position (Fig. 1); then the stream inhaled from the hand, FIG. First position of the head, in wbicu the anterior third of the nasal passages iswashed by the inhalation of water and air from the palm of the hand. will go upward and forward at an angle of 45°. In thisposition of the head, gravitation causes a part of the inhaledsolution to fall on the most anterior portion of the the inhalation of one or two handsful, the patientshould blow the nose, to free it of all liquid and loosened se-cretions. Continued and hard blowing of the nose should,however, be avoided, as this is liable to force mucus up theEustachian tubes, as well as to aggravate the congestion of theinflamed mucous membrane. To wash the middle third of the nasal parages, the headshould be inclined forward until the forehead is placed at anangle of 45 0 with the horizon (Fig. 2), then the greater part FIG. II.
