As arule it may facilitate the exami-nation to have the angle a littleless obtuse than for laryngoscopy, but a slight bending of the stemwill do all that is necessary, and very great variations can be ob-tained by depressing or raising the handle. Seated in front of the patient just as for laryngoscopy, theobserver uses the tongue depressor with one hand and introduces themirror with the other. The tongue depressor may eventually bediscarded, but at first is generally indispensable. In trying toassist, the patient often only makes difficulties, since the position of.

Combinations ofmirrors and depressors have been constructed but are apt to proveonly hindrances. The patient can easily himself hold a suitabledepressor such as Tlircks or the writers, and then the physicianwill have both hands free. The greater the space between the poste-rior wall of the pharynx and the velum the easier it will be to illu-minate the nares. When this space is excessively narrow, it may beimpossible to obtain a satisfactory view of the parts. On looking into the mouth, the soft palate may not infrequentlybe seen to be closely applied to the pharynx, instead of hanging freelyso as to permit the mirror to be passed behind it. This is causedby the patient breathing through the mouth, a
