HISTORY OF SAMPLES. 



Most of the samples of breaking-stock eggs used for tlie investiga- 

 tion were procured from the current receipts of commission houses 

 located in an eastern consuming center. In a few instances in the 

 beginning of the season samples were purchased from grocery stores. 

 Late in the season the samples consisted of breaking-stock eggs 

 sorted from eggs coming from storage. The firms from whom most 

 of the samples were obtained operated egg-breaking plants in addi- 

 tion to their wholesale business. Most of the eggs were produced 

 either in the Middle Western States or in Virginia, and were shipped 

 to the consuming center; after the weather had become warm, in 

 refrigerator cars. The time occupied in making the haul varied from 

 3 to 12 days. The history of each sample is given in Table I.

NUMBER OF EGGS CONTAINING BACTERIA. 



Only a few of the individual eggs examined contained appre-
