that the housewife terms "" eggy " or " strong." If the odor is not 

 bad and if the mixing of the yolk and white is slight, the housewife 

 uses these eggs for general cookery, though when the whites are to 

 be whipped separately to lightness they are not satisfactory. The 

 egg shipper does not attempt to send such eggs on long or hard jour- 

 nej's, because this mixing is accelerated by jarring; nor does he at- 

 tempt to store them, because white and yolk continue to mix more 

 and more rapidly. These eggs are therefore used very largely by 

 the breakers. They should be examined very carefully for odor and 

 appearance when broken, as they msij be incipient forms of the "sour 

 egg^' (see p. 61). Table 9 illustrates the condition of this series.
