variable, it is not possible to judge the quality of the liquid egg from the quantity 
found in dried egg, or vice versa. 
A comparison of the amount of ammoniacal nitrogen and the bacterial content of 
dried whole egg, dried mixed egg, and dried yolks shows, as can be observed in Tables 
E-V, F-II, and F-IV, a tendency to greater quantities of ammoniacal nitrogen when 
the product is heavily infected with bacteria, but the relation between the two is 
far from being as definite or as conclusive as when the tests are applied to liquid egg. . 
COMPARISON OF THE LIQUID PRODUCT FROM THREE HOUSES IN 1912.. 
There was but slight variation found in the amount of ammoniacal nitrogen in the 
commercial liquid products prepared by the cooperating houses in which the mode 
of preparation was thesame. The average bacterial contents of the liquid products 
of D and F houses, which derived their breaking stock mostly from their current 
receipts, were nearly the same. The number of bacteria in the liquid egg of E 
house was greater than for the other two houses. The latter purchased its breaking 
stock from other houses; consequently it was somewhat older at the time of break- 
ing than that of the other two houses. The data summarizing the findings for the 
three houses are given in Tables 8, 9, 10, E-VIII (Appendix), and F—XI (Appendix).
