will vary widely. However, the best estimate possible was made to 
determine this point, after which the measurements on 50 bottles 
were averaged. The aim. determined by the manufacturer of the 
bottles, was the height to which he usually fills to make his tests as 
to capacity. A recapitulation of the data, showing the average 
capacity of the bottles measured and the capacity from the base of the 
shoulder to the top and from the aim to the top, with their relations 
to the calculated maximum variations, is given in Table 8.

The calculated maximum variations average nearly 0.3 of the avail- 
able space from the base of the shoulder to the top in cylindrical-neck 
bottles and nearly 0.3 in conical-neck bottles; that is, the bottler has 
about three times enough room in his filling range to adjust his
