\Ve may add this statement to the rule : that if the atomic 

 weights are from Clarke's 1 902 list with hydrogen as Unit, 

 then the greatest difference between the computed and the 

 determined value will not exceed 4 units, nor will the per- 

 centage difference be greater than 6 ; while in 36 cases the 

 result will not be a unit wrong, and in 19 cases will not he 

 1 per cent, wrong.
