1^4 Anahfis of the Air. 



Experiment LXIL 



From about a cubick inch of chymical 

 Oil of Annifeedy I obtained 22 cubick inches 

 of air ; and from a like quantity of Oil of 

 Olives 8 8 cubick inches of air. The rea- 

 fon 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- 

 ed 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- 

 eft part of the retort, whereby more air 

 was feparatedj yet in this cafe good ftore 

 of Oil came over into the receiver ,• 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 Mu (lard- feed, than it is from expreff- 

 ed or chymical Oil.
