No. 56— 1905.] SINHALESE COPPER MASSAS, 399 
There were four kings named Bhuvaneka Bahu, but only 
the first two are in the period dealt with, viz., Bhuvaneka 
Bahu the First, 1277-1288, and Second, 1293-1295. 
The gap between Vijaya Bahu I. and Bhuvaneka Bahu I. 
is one hundred and fifty-seven years. And within this 
century and a half the other four coins of these notes were 
current. This being the case, it is natural to expect that 
such diflEerences as exist between the coins issued by these 
four rulers will form some sequence of style, connecting 
the coins of Vijaya Bahu with those of Bhuvaneka Bahu. 
But this is not by any means borne out by observation. 
Far from representing the two opposite ends of a series 
they resemble each other much more than they do the 
pseudo intermediate issues. The points especially to be 
noted are as follows : — 
(i.) Size. — Measuring a large number of each king's coins 
I found the averages to work out as follows 
Parakrama Bahu, diameter averages ... 
19*44 millimetres 
Sahasa Malla, 
do. 
20-20 
do. 
Lilavati, 
do. 
20-47 
do. 
Dhammasoka Deva, 
do. 
20-40 
do. 
Bhuvaneka Bahu, 
do. 
19-00 
do. 
Yijaya Bahu, 
do. 
19-17 
do. 
(ii.) Weight. — Here again the difference, though slight, 
bears out the measurements. Figures in brackets represent 
the number of coins weighed to obtain an average. 
Parakrama Bahu (100), average weight of each coin 420 milli- 
grammes. 
Sahasa Malla (100), average weight of each coin 440 milli- 
grammes. 
Lilavati (68), average weight of each coin 426 milligrammes. 
Dhammasoka Deva (11), average weight of each coin 427 milli- 
grammes. 
Bhuvaneka Bahu (52), average weight of each coin 413 milli- 
grammes. 
Vijaya Bdhu (86), average weight of each coin 407 milli- 
grammes. 
(iii.) Metal, — The coins of Parakrama Bahu, Bhuvaneka 
Bahu, and Vijaya Bahu corrode green, sometimes with a red 
crust.
