ROMAN POTTERY FOUND IN BRITAIN. 
addition of a pedestal or expanded foot. This useful addition was 
not, however, restored upon the later revivals, which have an 
inferior holding capacity and unserviceably contracted base. 
In preparing the following tables of standard proportions, due 
regard has been paid to the origin of the various types. It should 
also be stated that the possibility of preparing them is due to the 
accurate and complete dilineations of the types furnished by 
German archaeologists, and by recent writers in this country, who 
have commenced to supply drawings of the principal types as 
well as photographs of each vessel or fragment. This applies 
especially to Mr. Curie’s Newstead volume. 
Unnecessary trouble may be avoided in preparing and referring 
to the tables, when only photographs and drawings of small size 
are available, by employment of the metric system and taking the 
measurements to the nearest millimetre, or half-millimetre, and 
by calculating the proportions with a logarithmic slide-rule. 
Though many of the proportions in these tables have been 
obtained from small drawings and photographs on which there is 
always a certain amount of fore-shortening, and may require 
revision from direct measurements, this does not interfere with 
the accuracy of the comparative results. On comparison of the 
results for the beginning and end of the four centuries of the 
Roman occupation given in the last column (proportion of the 
base diameter to the height taken as ioo), the amount of the 
attenuation is seen to be about half in tables I. and III. In 
table II. the diameter of base has dwindled to less than one third 
of the original, or to less than one fourth of the height of the 
vessels, giving the latter a top-heavy and unstable character. 
For the approximate dates of vessels belonging to the series of 
grave groups in the Provincial Museum in Trier, acknowledgment 
is due to Dr. E. Kruger, director of that museum. 
Mr. Arthur G. Wright, Curator of the Corporation Museum, 
Colchester, has kindly looked over the proofs.
