Experiment V* 
T? Eing a New Experiment with Ebullition and incale 
^ fcencc. 
Amongft thofe various mixtures , wherein great Heats 
and Effervencies with much Ebullition were produced, 
none were fo confiderableas this, which was alio fliewn 
at the fame Meeting, 
Upon an Ounce of spirit of Nitre, if you pour two or 
three Drams gradually of the higheft redified Spirit <£ 
Wine^ the Heat and Ebullition will be incredibly great.
