posterior to anterior lines, when tlie "thorough 

 action " of the head sockets passes the lines from 

 the shoulder-blades to the lower jaw, and the upper 

 C C of the lung tips on the passage from anterior 

 to posterior lines, when the "thorough action " of 

 the head condyles passes them from the lower jaw 

 to the shoulder-blades. Also that each lung lobe, 

 upper or lower, is exhausted and filled through its 

 collateral nostril. 



That when both upper and lower lobes are filled, 

 the pressure from the lower lobes, if the filling of 

 these through the nostrils be continued, may be 

 made to drive out the air- from the upper lung 

 lobes, through the mouth, and that a long protrac- 

 ted, if not indefinitely contiuued, current of air 

 may thus be kept up, on which the vocal chords 

 may act, as the cords of any stringed instrument. 

 Of the volume of sound created, and of the ease 

 with which it may thus be produced, Mons. 

 Morquin gave repeated proofs. 



§ 184. Mons. Morquin, so far as we know, made 

 no attempt at any anatomical explanation of the 

 system, which, he said, had been taught him, as 

 one of the soldiers of a battalion selected for gym- 

 nastic instruction, and which, at the time of the 

 French Revolution of 1830 was stationed at Rheims.
