Common Spirit of Nitre, fuch as was firft diftiirdinto

it muft be the spirit of Nitre^ and a very high rc^li-

into your Glafs ihe spirit cf Nitre^ which is the heavier 
Liquor^ and then the tpiritoiWinedik^t^ for if yon invert 
the order you will have no Ebullition, which will not a

In this Experiment ( efpecially if the Ingredients are made 
very high^ the Spirit of Nitre does as it were zdi the part 
of a Coal of fire : as fire exhales and drives up rpater that is 
thrown upon it, fodoes this Spirit of Nitre very furioufly 
throw up a great quantity of the Vinousfpirit, in fomucn 
that it prefently perfumes a Room with the fmell;but to be
