 of the whole, lb one ounce was loft in the 

 operation. 



In my diflillation of 443 grains of Tar- 

 tar in Exper. 73. 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

 diflillation together, we (hall rind, that there 

 remained in this 32 ounces of Scoria, and 

 in the ounce that was ioft, ( which was 

 doubtlefs moft of it air) fubftance enough 

 to account for the great quantity of air, which 

 in Exper. 73. was raifed from Tartar*, efpe-

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

 tar, for there is much air in oil.
