VOLUME VARIATION OF BOTTLED FOODS. 



15 



in Virginia, West Virginia, and Maryland were visited, and 20 sets 

 of measurements, including 524 bottles, were taken. Rough measure- 

 ments were first made on the bottles being used, from the result of 

 which the bottler was given an aim in ounces by which to fill 50 

 bottles for measurement. The aim given was as consistent as possible 

 with his declaration of the quantity of contents, but slight changes 

 were often made, even though he were approximately following the 

 good commercial practice outlined in this bulletin. The bottler was 

 then requested to fill a number of his bottles with the specified number 

 of ounces given to him as an aim, take the average of the distance 

 from the top, and adjust his filling machine or filling system to fill 

 to this average height. In cases where allowance for contraction due 

 to change in temperature was necessary, he was instructed to deliver 

 bottles which would be filled to this aim when cool. In cases where 

 the bottles could not be opened, such as soda water, 50 empty bottles 

 were selected at random, paired with full bottles, and filled to the 

 same height by pouring water from a standardized graduate. The 

 results so obtained were assumed to be equivalent to the volumes of 

 food contained in the original bottles. 



The results obtained are recapitulated in Table 5.

With the exception of one set of data, measurements were taken on 

 bottles of soda water and vinegar, and data were taken on hand- 

 blown and machine-blown bottles, round and square bottles, bottles 

 with conical and cylindrical necks, jars, and jugs. Some of these
