2 74 Anal^fis of the Atr. 
Experiment LXII. 
From about a cubick inch of chymical 
Oilof Annifeedy I obtained 22 cubkk inches 
of air ; and from a like quantity of Oil of 
Olives 8 8 cubick inches of air. The rea* 
foil of which difference was, as I fuppofe, 
this, viz. finding that the Oil of Annifeed 
came plentifully over into the receiver, in 
the diftillation of the Oil of Olives, I raif- 
cd the neck of the retort a foot higher, 
by which means the Oil could not fo eafi- 
ly afcend, but fell back again into the hot- 
cft part of the retort, whereby more air 
was feparated; yet in this cafe good ftore 
of Oil came over into the receiver j in 
which there was doubtlefs plenty of un- 
elaftick air : Whence by comparing this 
with Experiment 58. we fee that air is in 
greater plenty feparated from the Oil, when 
in the Muftard-feed, than it is from exprcff- 
cd or chymical Oil.
