GROWTH OF THE INNER EAR OF ALBINO RAT 13 



A. On the growth of the radial distance between the two 

 spiral ligaments (fig. 3, 1-1, 2-2) 



As we have usually four sections of the ductus cochlearis, 

 therefore four spiral ligaments in one radial vertical section, 

 there are two radial distances presented, the first, figure 3, 1-1, 

 connecting the two basal sections of the ductus on opposite 

 sides, and the second, figure 3, 2-2, connecting the two apical
