Although the variation, shown in Table 17, in the number of bac- 

 teria in the different lots of cracked eggs was almost the same as 

 that found in the samples of seconds, the individual counts in many 

 instances were higher. For instance, 43.8 per cent of the samples 

 of checks, as compared with 66.6 per cent of the samples of seconds, 

 had counts under 200,000 per gram. The damaged shell of the 

 checks offers less resistance to bacterial invasion than do sound 

 shells, which factor explains the higher average count of cracked 

 eggs. As was the case with the types of eggs previously discussed, 

 the samples with the liighest bacterial content were those which were 

 taken during the month of August. The samples showed no greater 

 deterioration chemically than did the specimens of summer firsts, 

 seconds, and dirties. 



Eggs with incipient odors but norma:! in appearance are very 

 often found in some lots of cracked eggs, particularly in those which 

 have not been chilled previous to opening. An examination of four 

 single eggs gave counts of 12,000 bacteria per gram or less in three 

 samples and of 1,200,000 in the fourth. There was no abnormality 

 in the latter to distinguish it from the other three. A fifth sample
