Comparison of PS with ea ch of the weights T + Q + A , T + Q + B , T -j- Q -f- C, T -j- Q + D . 
7’he weights Q were changed, so that each of the ten weights Q was used the same 
number of times in each series of weighings. The cistern of the barometer was 305 mm. 
above the weights. Therefore 0‘03 inm. must be added to F.
