In a.(<= 1 6*24,6= 762*68) counterpoise balances the wire loop inw. + K + L + (2) + (l) + 0*4855gr. + P + Q + R. 
A correction must be applied for the change of density of the air displaced by the 
counterpoise after C was taken out of the water. When 0 and the wire loop were 
in the water, 15*07, &=763‘08. When the wire loop alone was in the water and 
weights in the right-hand pan, 16*24, &=:762‘68. The counterpoise displaces 
2*0453 grs. of air (#=16*07, 6=76*308), and 2*0429 grs. of air (#=16*24, 6 = 762*68). 
14003 — 2*0453 grs. balance ® and wire loop in water (#=15*0)-}- 0*00 10 grain in air.

P+Q+R=700*003 grains nearly. 
G + K+L + M + (l6) + (4) + 0*00242=699*93747 grains. 
The weights of the air displaced by the bronze and platinum weights are 0*10668 gr. 
and 0*04217 gr. respectively. Hence P-|-Q-|-R=700*00197 grains. 
The weight of air displaced by the platinum and bronze weights used in weighing
