The spatular end of the laryngoscope is introduced in
the right side of the patient's mouth, along the right side of the
anterior two-thirds of the tongue. It was the German method to
introduce the laryngoscope over the dorsum of the tongue but in order
to elevate this sometimes powerful muscular organ considerable force
may be required, which exercise of force may be entirely avoided by
crowding the tongue over to the left. When the posterior third stage
of the tongue is reached, the tip of the laryngoscope is directed
toward the midline and the dorsum of the tongue is elevated by a
lifting motion imparted to the laryngoscope. The epiglottis will then
be seen to project into the endoscopic field, as seen in Fig. 54.

tip on the tongue anterior to the epiglottis.]
