The best experiments on the expansive force of steam are 

 those of Dalton, comprehending all temperatures between the 

 freezing and the boiling points ; and those of Dr. Ure, which 

 extend from the freezing point to 312°. We have also, more 

 lately, a Table of results by Mr. Philip Taylor, from 212° to 

 320° f, which added to Mr. Dalton's Table completes the 

 same range of temperature as the experiments of Dr. Ure. 

 The three Tables we have mentioned are nearly on equal 

 footing in point of accuracy; but in a research like the pre- 

 sent, it seems better to adopt, as die foundation of our reason- 

 ing, the results obtained by one observer, and by the same 

 uniform processes. For this reason the experiments of Dr. 

 Ure are made the ground work of the following Table :
