The data contained in table B was obtained for the hydrogen 

 directly filling the eudiometer from the delivery tube of the 

 purifying train. The last example was obtained for the 

 hydrogen which was previously compressed in the measuring 

 tube at atmospheric pressures and then delivered into the 

 eudiometer. The sign of the change of reading is positive 

 when the volume of the gas increases, and negative when it 

 decreases ; and therefore the negative sign in the last
