The numbers in the columns headed Sp-j-X, P+Y, Sp + Y, P+X are the readings 
of the scale in the positions of equilibrium of the beam with the counterpoise in the 
left-hand pan, and the weights Sp-fX, P-l-Y, Sp+Y, P+X respectively in the right- 
hand pan. The scale readings of the alternate weighings are arranged in separate 
columns for the sake of greater convenience in adding up the results.
