A result so strikingly at variance with all earlier researches must be 

 subjected to most critical examination and control. It is possible, for 

 example, that the apparatus was mechanically so constructed that the 

 manometer is more readily set at zero when the mercury in the pipette B 

 is at 20.94 per cent a condition difficult to conceive, but nevertheless not 

 absolutely impossible.
