Statistical Summary of Field Experiments 



For the sake of convenient reference a summary of the statis- 

 tical data presented in the preceding pages is appended in tabular 

 form and in numerical order (table 9). The number of the 

 sample, the character of the organism employed or of the sample, 

 tlie designation of the organism, the bacterial count per cc. of 

 the sap, and the reaction of the sap in percent of N/100 aeid 

 occupy the first five columns respectively. These are followed 

 by the percentages of sucrose and invert sugar in the sirups, 

 calculated to a dry matter basis. The numbers in the column 

 headed "ratio" were obtained by dividing the percent of sucrose 

 by the percent of invert sugar. A small ratio number, there- 

 fore, indicates a relatively high proportion of invert sugar and 

 a high number, a small proportion. The ratio numbers with their 

 corresponding invert sugar values are shown below in tabular 

 form :

Following the ratio column are given the values for color, 

 flavor and score, assigned to the various sirups, and also the de- 

 preciation in color, flavor and score of inoculated sirups from 

 the corresponding value assigned to their respective controls. A 

 date column completes the table.
