12. The correlation between either of the two large parts 
and the whole egg when the other part remains constant is high 
and shows insignificant individual differences. The albumen- 
weight correlation is slightly* higher than the yolk-weight 
correlation. 
13. The correlation between albumen and yolk is higher than 
the correlation between either of these and shell. In general 
the albumen shell correlation is higher than that for yolk and 
shell. The range of correlation for any of these pairs of char- 
acters, however, varies in different birds from insignificance to 
high correlation. 
14. In eggs of the same weight any two parts are negatively 
correlated. The yolk-albumen correlation is highly negative 
and the different individuals show little variation in the value 
of the coefficient. The yolk-shell and albumen-shell correla- 
tions are significantly negative for most individuals but the 
value of the coefficients for the different individuals varies 
greatly. 
15. Length and breadth are positively correlated with the 
weight of each part of the egg. When there is a significant 
difference between the correlation of length and any part ana 
the correlation of breadth and the same part the breadth corre- 
lation is higher.! There is, however, a great deal of individual 
variation in the degree of these relationships. 
16. Albumen and yolk correlations with either dimension 
are higher than the shell correlation. Albumen correlations are 
significantly higher than yolk correlations for several individ- 
uals. The reverse is true in only one case. 
17. In eggs of the same weight the correlation of either 
dimension with any part is often not significant. The different 
birds show a great deal of variation in these coefficients. The 
most usual relationship is for breadth to be positively correlated 
with yolk and negatively correlated with albumen and shell. 
An Analysis oe the Variation Among the Eggs oe the 
Same Bird. 
It has been shown that while the eggs of an individual 
resemble each other more closely than do eggs forming a 
* This difference may not be significant, 
t There are two exceptions to this statement.
