THE DIAMETERS OF INDIVIDUAL EGGS. 



In the two preceding tables the measurements are given for 

 groups of ten eggs each. Comparison of the various sets indicates 

 considerable variability, but the true extent of this can only be 

 realized when a large number of ova is treated individually. 

 This was done with 100 eggs of female B and 100 of female C. 

 The results are given in Tables III. and IV. 



TABLE III. 



Average of 3 = 57.1 

 Average of 3 = 65.5 

 Average of n = 70.8 

 Average of 16 = 74.2 

 Average of 15 = 79.2 

 Average of 20 = 82.6 

 Average of 14 = 84.5
