The pressure by weights was invariably higher than by crusher ; 

 at 5 tons (by crusher) the difference was about 11 per cent., at 6 tons 

 about 9 per cent., at 13 tons about 11 per cent., at 16 tons about 

 16 per cent. At 5, 6, and 13 tons there is usually (but not always) 

 less difference between the individual pressures by crusher given 

 above than between the weights pressures ; at 16 tons there is 

 decidedly greater regularity in the crusher results than in those by 

 weights; the crusher pressures are, however, the means of series,. 

 which favours them somewhat.
