The volume of gas at the mean was therefore 51 ,20 cubic 
inches. 
100 : 57,50 :: 51,20 : 29,44. 
Then 29,44 cubic inches of carbonic acid gas were produced. 
100 : 47,26 : : 29,44 : 13,91. 
13,91 : 4,01 : : 100 : 28,82. 
Then, according to this experiment, 100 grains of carbonic 
acklcontain 28,82 diamond.
