The marginal proportions in the last two columns indicate variations in the 
diameter and altitude of the bulge. The mode of obtaining them is explained 
on page 34. Their use is to make it possible to determine the approximate date 
of fragments large enough to furnish one or other of these proportions. 
The table reveals the gradual decrease of the width of the bulge of oil®,— 
the other two dimensions (width of rim and base) undergoing little change in 
the course of development. Before a.d. 150 the width is greater than the height 
of the vessel, but rises to as much as 20 % more. After that date the width 
is always less than the height, and falls to as much as 25 °/ Q less. Before a.d. 
150 the upper margin (rim) is never less than 20°/ o , nor the lower one (base) less 
than 40%, but afterwards the former sinks to less than o, and the latter to 
2 3 %■
