Less than 100. 
The lowest number of bacteria found at i^O^ C. was SlX"^ per gram 
in a sample taken during the early part of May. and the highest. 
3,600.000. in a sx^ecimen 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 21- lots of whole egg only about S per cent 
had more tlian S50.000. There were no B. coll in 11, or 35 per cent. 
and 100.000. or less, in tlie remaining samples. The percentage of 
ammoniacal nitrogen varied from 0.0015 per cent on the wer basis 
in spring seconds to 0.0026 per cent in summer seconds. 
A larger mmiber of eggs was discarded Avhile breaking the summer 
and fall seconds than when opening analogous eggs in the spruig. 
It is probable that the organisms in the sainple> of liquid egg from 
seconds are referable partly to otitside source.-, but chiefly to the eggs 
themselves. 
EGGS HA^TS^G DIRTY SHELLS. 
The highest percentage of dirty-shell eggs occurs dtiring tlie 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 Augxist. 1912. Fifteen dozen eggs were represented 
in one sj)ecimen and 6 dozen in the other five. All of the eggs were 
candled before opening. The ntimber of eggs discarded during the 
process of breaking gives, perhaps, an. index to the cpaality of the 
eggs in the different samples. Xot- more than three decomposed eggs 
were eliminated from the samples taken during jlay and June and 
not more than six from the two specimens broken in August.
