Anahfis of the Air. 



Experiment LXII. 



From about a cubick inch of chymical 

 Oil of Annifeedy I obtained 22 cubkk inches 

 of air ; and from a like quantity of Oil of 

 Olives 8 8 cubick inches of air. The rca- 

 fon of which difference was, as I fuppofe 

 this, viz. finding that the Oil of Annifccd 

 came plentifully over into the receiver, in 

 the diftillation of the Oil of Olives, I raif- 

 ed the neck of the retort a foot higher, 

 by which means the Oil could not fo cafi- 

 ly afcend, but fell back again into the hot- 

 eft part of the retort, whereby more air 

 was feparated; yet in this cafe good ftorc 

 of Oil came over into the receiver j in 

 which there was doubtlefs plenty of un- 

 claftick 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 expreiT- 

 ed or chymical Oil.
