During the vocalization of sounds that passedthrough the mouth alone, the soft palate was raised, and about4 of its lower border was pressed against the posterior wallof the pharynx (Tig. 5 >. From repeated inspections made while the velum was in eachof these two positions, it appeared that all the sounds wereuttered without the aid of either the uvula or the azygos prom-inence. The favorable opportunity for observing what assistance isrendered by the azygos prominence and the uvula is during thephonation of such sounds as are required to pass through themouth and nose at the same time. While these sounds wereuttered, the soft palate was either suspended, so that but a. Figure 6. View of the anterior surface of the soft palate, the uvula and the base ofthe tongue, showing the lower semi-lunar-shaped openings (S-l.) formed bythe uvula (U.) and a part of the central portion of the velum resting on thebase of the tongue (B. T.) small part of its central portion of the uvula rested on the baseof the tongue (Fig. 6), or it was raised to such a height thatthe azygos prominence touched the posterior wall of the phar-ynx (Fig. 3). In each situation that the velum occupied, thecommunication between the fauces and the mouth, and be-tween the fauces and the pharyngo-nasal cavity, was dividedinto two equal, or nearly equal, semi-lunar openings. In thefirst position named, the division was made by the uvula anda small part of the central portion of the velum resting on thebase of the tongue (Fig. 6, S-l), and in the second position thepartition was made by the azygos prominence (Fig. 3, S-l),touching the posterior wall of th
