(b) tests representative samples of every lot of bottles received,, 
rejecting those appreciably under capacity, (c) fills his bottles to 
a height determined from the results of his tests, and (d) has his 
labels printed with a definite, correct statement of the quantity of 
contents and applies them unaltered. 
The calculated maximum variations in the volume of bottled foods, 
as given in Table 9, have been computed from the weight variation 
allowed the bloAvers by the manufacturers, and by the use of the 
relation between the weight and volume of bottle glass.

Data on the capacity of bottles and volume of food in bottles indi- 
cate that only a small percentage of the bottles of food filled in 
accordance with good commercial practice, as outlined in this bul- 
letin, should vary in quantity of contents by more than the calculated 
maximum variations.
