 senting the vestibulum and semicircular 

 canals laid open, and the branches of the

PLATE III. 

 Fig. 1- ^9 front view of the muscles. 



The right side of the figure represents 

 the first or most superficial stratum : on 

 the left side the second layer is exhibited. 

 It would be impossible to refer to all the 

 muscles exhibited in this and the follow- 

 ing muscular plates : we must therefore 

 confine ourselves to the more obvious and 

 important ones.
