to compare, were made with the greatest care, and as 

 they are on several accounts uncommonly interesting, I 

 shall place them in a conspicuous point of view. 



A COMPARATIVE VIEW OF TWO EXPERIMENTS MADE 

 WITH A NEW BREWHOUSE BOILER. 



The time is reckoned from the beginning of the Experiment, and was 

 the same in both Experiments.

Having found, by comparing the results of these two
