Lemery, in his courfe of chymiftry, p. 592. 

 obtained in the diflillation of 48 ounces of 

 Tartar, 4 ounces of phlegm, 8 of fpirits> 

 3 of oil, and 32 of Scoria, /. e. two thirds 

 of the whole, fo one ounce was loll in the 

 operation. 



In my diflillation of 443 grains of Tar- 

 tar in Expcr. 7 3- there remained but 42 

 grains of Scoria, which is little more than 

 h of the Tartar ; and in this remainder, 

 there was by Exper. 74 Air, for there was 

 Sal Tartar, it running per deliquium. 



Whence by comparing Lemery's and my 

 diilillation together, we (hall find, that there 

 remained in this 32 ounces of Scoria, and 

 in the ounce that was loft, ( which was 

 doubtlcfs moil of it air) fubftance enough 

 to account for the great quantity of air, which 

 in Exper. 73. was raifed from Tartar; cfpe- 

 cially, if we take into the account the pro- 

 portion of air, which was contained in the 

 oil, which was r 6 part of the whole Tar- 

 tar, for there is much air in oil.
