GROWTH OF THE INNER EAR OF ALBINO RAT

Looking at the diameters of the cell bodies and their nuclei 

 in each turn (table 101), we do not find in the later age groups a 

 regular increase in passing from the base toward the apex, as 

 in the cells on the radial section. The differences are generally
