I Less than 100. 



The lowest number of bacteria found at 20° C. "was 300 per gram 

 in a sample taken during the early part of May, and the highest, 

 3,600,000, in a specimen obtained during the latter part of August. 

 Of the 16 samples of "whites and yolks none contained over 650,000 

 bacteria per gram ; of the 24 lots of whole egg only about 8 per cent 

 had more than 850,000. There were no B. coll in 14, or 35 per cent, 

 and 100,000, or less, in the remaining samples. The percentage of 

 ammoniacal nitrogen varied from 0.0015 per cent on the wet basis 

 in spring seconds to 0.0026 per cent in summer seconds. 



A larger number of eggs was discarded "while breaking the summer 

 and fall seconds than when opening analogous eggs in the spring. 



It is probable that the organisms in the samples of liquid egg from 

 seconds are referable partly to outside sources, but chiefly to the eggs 

 themselves. 



EGGS HAYING DIRTY SHELLS. 



The highest percentage of dirty-shell eggs occurs during the wet 

 spring weather. Since they do not keep well in storage, a large num- 

 ber find their way to egg-breaking establishments. 



Table 16 gives the laboratory findings of six samples taken during 

 May, June, and August, 1912. Fifteen dozen eggs were represented 

 in one specimen and 6 dozen in the other five. All of the eggs were 

 candled before opening. The number of eggs discarded during the 

 process of breaking gives, perhaps, aru index to the quality of the 

 eggs in the diiferent samples. Not more than three decomposed eggs 

 were eliminated from the samples taken during May and June and 

 i}ot more than six from the two specimens broken in August.
