SIZE, SHAPE AND PHYSICAL CONSTITUTION OF THE EGG. Ill 
1. Different pairs of egg characters show a decided differ- 
ence in the degree of correlation. 
2. There is a general tendency for a given pair of charac- 
ters to be similarity related in the eggs of the several individ- 
uals. 
3. Individuals, however, show significantly different degrees 
of correlation in any pair of characters. The range of the 
individual variation is wider and the number of individuals 
which differ significantly from each other is larger for some 
pairs of characters than for others. 
4. Length and breadth are positively but not highly cor- 
related. 
5. Both length and breadth are highly positively correlated 
with weight. 
6. Breadth-weight correlation is as a rule higher than length- 
weight correlation but an individual may show the reverse 
relation. 
7. Index and weight correlation when significant is negative 
and low. 
8. The relation between length and breadth, length and 
weight, and index and weight is much closer within the eggs 
of an individual than within the eggs of the strain, but breadth 
and weight are as closely related within the eggs of the strain 
as within the eggs of an individual. 
9. In eggs of the same weight the two dimensions are nega- 
tively correlated but the degree of correlation varies greatly 
in the different individuals. 
10. Either dimension is highly correlated with weight when 
the other dimension is constant. The correlation between 
breadth and weight is higher than the correlation between 
length and weight. The individual variations are less than in 
the gross correlations or in the correlations between length and 
breadth in eggs of the same weight. 
11. The weight of each of the three parts of the egg (albu- 
men, yolk and shell) is positively correlated with egg weight. 
The heaviest part, albumen, is invariably very closely correlated. 
Yolk is also closely correlated but there is a greater individual 
variation in the value of the coefficients. Shell, the lightest part, 
is much less closely correlated and the individual differences 
are much greater than in the case of the two heavier parts.
