other characteristics are normal, but that eggs showing more advanced 
decomposition should be avoided. This phase of the egg problem will 
be specially investigated during the season of 1913. 
BLOODY WHITES. 
Many of the first eggs laid by pullets contain blood which may 
be diffused through the white or may be in the form of clots on the 
-yolk or in the albumen (see PL IV). It is probable that in the 
passage of the white and yolk through the oviduct some of the small 
blood vessels are ruptured, thereby allowing blood to gain access to 
the wliite or yolk before they are incased in a shelL 
The examination of six individual eggs of this type disclosed the 
presence of less than 5,000 organisms per gram. Xo B. coil were 
found, except in one sample, which had only 10. The eggs were 
taken from the cups of the breakers ; consequently the few organisms 
found are very likety referable to outside sources and not to the eggs. 
On account of the presence of blood, these eggs are not used for food 
purposes. 
EGGS WITH BLOOD RINGS. 
Eggs showing signs of incubation were discussed quite fully on 
page 13 ; consequently only the information gained when these eggs 
were broken commercially will be given here. 
During May, 1912, four samples, consisting of from 3 to 12 large 
blood rings, were taken. Since the weather had not been warm 
enough to cause spontaneous development of embryos of fertile eggs, 
these blood rings were probably the result of the undesirable ]3ractice 
of selling incubated eggs which would not hatch. The yolks were 
broken and partially mixed with albumen; the germinal disk was 
deteriorated. The odor of each was good.
