go Of the Management of Fire 



with the mean results of two other like experiments 

 made with the same boiler. 



On comparing the results of these experiments with 

 those made in the boilers of the kitchens of the House 

 of Industry and Military Academy, I was led to imagine 

 that either the boiler or the fire-place of the brewery, or 

 both, were capable of great improvement ; for, in some 

 of the experiments with these small kitchen boilers, the 

 economy of fuel had been carried so far that, with the 

 heat generated in the combustion of i Ib. of pine-wood, 

 it appeared that 20 'Ibs. of ice-cold water might have 

 been made to boil ; but here, though the machinery was 

 on a scale so much larger (and I had concluded, too 

 rashly indeed, as will be shown hereafter, that the larger 

 the boiler, the greater is of course the economy of fuel),
