PLATE XII. 
ILLUSTRATING THE PAPER OF WARREN H. EVERETT, p. 176. 
Fic. 1. The membranous ear as seen from the outside at nearly right 
angles to the side of the head and a little above. It shows the shape and po- 
sition of the sacculus (s.), utriculus (u.}, lagena (1.) and their relation to 
each other: also the position of the ampullze with respect to the canals and 
the recessus utriculus (r. u.). d. ¢. p. represents the small connecting tube 
between the connecting tube of the posterior canal (p. ¢. t.) and the saccu- 
lus (s. ). 
Fia. 2. The membranous ear as seen from the inside at right angles to 
and on a level with the head. It shows the position of the ductus endolym- 
phaticus (d. end. ) and its relation to the sacculus (s.), utriculus (u.) and the 
recessus utriculus (r. u.). It also shows the position of the utriculus (u. ) 
with respect to the recessus utriculus (r. u.) and the ampulla of the anterior 
canal (a. a.). The two dotted lines that extend from the ramulus of the 
posterior ampulla to the ductus canalis posterioris (d. ¢. p.) show the course 
of the ramuli of the macula neglecta. (m. n.) marks the macula.
