ly made, that a Candle which burnt 70" in a 
very dry receiver, burnt but 64" in the fame 
receiver, when filled with the fumes of hot 
water; and yet abforbed one fifth part more 
air, than when it burnt longer in the dry air. 
Sulphur not only abforbs the air when 
burning in a homogeneal mafs, but alfo in 
many fermenting mixtures 5 and as Sir Ifaac 
Newton obferved the attractive and refraCHve 
power of bodies to be greater or lefs, as they 
partook more or lefs of fulphureous oily par- 
ticles 5 fo there is good reafon from thefe 
Experiments to attribute the fixing of the 
elaftick particles of the air to the ftrong 
attraction of the fulphureous particles with 
which he fays it's probablq that all bodies 
abound more or lefs. Electrical bodies are 
alfo obferved to attrad more ftrongly, in 
proportion to the greater quantity of iulphur 
which they contain. 
That great plenty of air is united with 
fulphur in the oil of vegetables, is evident 
from the quantity of air that arofe from the 
diftillation of oils of Annifeeds and Olives* 
in Experiment 62. When by fermentation 
the conftituent parts of a vegetable are fe^ 
parated, part of the air flies off in fermen- 
tation into an elaftick ftate s part unites with
