286 Mr. Children's Abstract of the Characters of 



substance several times, by taking care that each succeeding 

 pressure exceeds that of the preceding, in the same manner 

 as Wedgewood's pyrometers are used to measure any greater 

 degree of heat than what they have been formerly exposed to. 



It may be observed, that the application of these leaden 

 balls to determine the actual pressure, will not interfere with 

 the regular operation of a press, as the articles under pres- 

 sure may be in the press at the same time the balls are used, 

 which of course must be placed between separate plates.
