\ pi Analyjis of the Air. 



In my diftillation of 443- grains of Tar- 

 tar in Exper. 73. there remained but 42 

 grains of fcoria, which is little more than 

 ^ of the Tartar-, and in this remainder, 

 there was, by Exper. 74. air; for there was 

 Sal Tartar y it running /w deliquiunu 



Whence, by comparing Lemerys and my 

 diftillation together, we fhall find, that there 

 remained in this 32 ounces of fcoria, and 

 in the ounce that was loft, ( 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- 

 cially, if we take into the account the pro- 

 portion of air, which was contained in the 

 oil, which was tV part of the whole Tar- 

 tar, for there is much air in oil. 



The bodies which I diftilled in this man- 

 ner, ( Fig. 38. ) were Horn, Calculus huma?2us> 

 Oyfter-fhell, Oak, Muftard-feed, Indian- 

 wheat, Peas, Tobacco, oil of Anifeed, oil 

 of Olives, Honey, Wax, Sugar, Amber, Coal, 

 Earth, Walton Mineral, Sea-falt, Salt-petre, 

 Tartar, Sal Tartar, Lead, Minium. The 

 greateft part of the air obtained from all 

 which bodies was very permanent, except 

 what the air of Tartar and calculus humanus 

 loft in ftanding feveral days. Particularly chat
