Of the precautions to be obferved in the ap- plication of this ufeful inftrument. Of the Liquefactiony Melting, or Fufidn of bodies. Of their Volatilization, or converfion into va- poyrbrubric ip In this date1 they poffefs a high degree of Elafticity. Upon the expanfive power of voladzed water depends the effects of the Steam Engine. To the head of Evaporation m,ay alfo be re- ferred theproceffes of Diflillation, and Sublimation.

Hence the diflindlion between comhuflible and incombuftible fubftances.
