156 MARKETING AND GRADING EGGS 



"(e) Watery egg: Those in which the inner 

 membrane of the air cell is ruptured, allowing the 

 air to escape into the contents of the egg and thereby 

 giving a watery or frothy appearance. 



" (f) Presence of foreign matter in eggs: Small 

 blood streaks or clots. This condition is found in 

 many fresh laid eggs. Often eggs are laid which 

 show small clots about the size of a pea. These are 

 sometimes termed ' liver ' or 'meat ' spots. 



"(g) Badly misshapen eggs: Eggs which are 

 extremely long or very flat, or in which part of the 

 shell's surface is raised in the form of a ring; in 

 other instances a number of hard, wartlike growths 

 appear on the outside of the shell. 



" Spots : Eggs in which bacteria or mold growth 

 has developed locally and caused the formation of 

 a lumpy adhesion on the inside of the shell. There 

 are three well recognized classes of mold spots — 

 namely: white, brown, and black. In cases where 

 an infertile egg has been subjected to natural heat 

 for a sufficient period of time, the yolk will often 

 settle and become fixed to the membrane. This con- 

 dition might be termed a 'plainspot.' 



" Blood rings : Eggs in which the embryo has 

 developed to a sufficient extent so that it is quickly 

 recognized when held before the candle. It has been 

 found that it requires between twenty-four and 

 thirty-six hours of incubation under a sitting hen 

 to produce this condition.
