ANATOMICAL AND PHYSIOLOGICAL STUDIES ON 



As the tables and charts show, the diameters of the cell bodies 

 and also of their nuclei are largest at twenty days of age. After 

 that age they diminish gradually. While the ratio for one to 

 twenty days is 1:1.7 in the cell bodies and 1:1.3 in the nuclei, 

 that for 1 to 546 days is 1:1.6 and 1:1.2, respectively. 



TABLE 95 



Diameters of the cell bodies and their nuclei in the ganglion spirale (radial-vertical 



section) {chart 40) 



In table 96 (chart 41) are a series of computed diameters 

 of the cell bodies and of their nuclei according to the turns of the 

 cochlea. At the bottom of each column are given the ratios 

 from 1 to 20, 1 to 546, and 20 to 546 days. Determining the 

 ratios for each column, it appears that in general the diameters 

 of the cell bodies and their nuclei are largest at twenty days 

 throughout all the turns. This increase is very considerable from 

 fifteen to twenty days. Then they decrease very slowly till
