7. Amount of Analytical Work Required by the Investigation 
and Extent of Data Furnished. 
In order tv insure the greatest possible accuracy, every analyti- 
cal determination was performed three times; so that. in making 
analyses of the milk used in 106 experiments, an amount of ana-

samples of wilk. The same was true of the whey and cheese. The 
table below gives the number of different determinations as they 
were made each month.
