PC No. 4 displaces 0*40184 grain of air, P8 displaces 0*40181 grain. Therefore 
PC No. 4 = PS — 0'00314 grain. 
Determination of the volume of Professor' Schumacher’s pound Sp+V. 
The troy pounds Sp, Sb, K were returned to Professor Schumacher, accompanied 
by a platinum weight V of about 1240*53 grains which with Sp makes a pound of 
7000 grains.
