A manual of diseases of the throat and nose : including the pharynx, larynx, trachea, oesophagus, nose and naso-pharynx . open his mouth widely, and the light should bemade to fall rather lower in the fauces than when it is desired to examinethe larynx. The rhinal mirror should then be carried to the back of thethroat/ its upper border being a little below the curtain of the palate, andits face directed upward, so as to form an angle of about 135° with thehorizon. If the uvula happens to be drawn upward and backward, as isoften the case, the patient should be told to expire gently, or to producesome nasal sound, such as hang. Straining and forced inspiration must beespecially avoided. It is sometimes necessary to depress the tongue witha spatula, but the shank of the rhinal mirror generally answers sufficientlywell. It is a good plan to pass the small mirror between the anterior pillarand the uvula on one side first, and then to withdraw it and introduce itagain in the same manner on the opposite side. By slanting the mirror alittle laterally the posterior corners of the naso-pharynx with the orifice of.

Whenthe glass is held in a nearly perpendicular position, the upper part of thearching posterior wall of the pharynx can be perceived, but the laws ofperspective reduce this view to the narrowest limits. To inspect even oneside of the naso-pharynx thoroughly, however, it is often necessary to in-troduce the mirror several times, and to turn its reflecting surface in dif-ferent directions ; hence the post-rhinal image (Fig. 35) is a compoundpicture made up of many limi
