The comparable coefficients of variability, calculated on the basis of 

 unit classes, for the eggs used in compiling tables 52 to 54 are: for size 

 (table 52), 20 per cent; for shape (table 53), 10 per cent; for color (table 54), 

 74 per cent. The greater irregularity in the color of eggs as compared

with the other characters undoubtedly accounts for the results in this 

 one correlation with the pullets' eggs incubated. The coefficients of 

 correlation for the study of the mean production with the hens' eggs are 

 positive for all characters and years. The color correlation is about as 

 significant as the shape correlation.
