on the Production of Dephlogijlicated Air . I2 ^ 
raw filk, were expofed from Sunday noon, September loth, 
till Monday evening, the weather being cold, with many flying 
clouds, in all about 6 or j hours fun. 
The airs produced were as follows. 
Quantity. Quality. 
By the globe A, with green water and 4 peach leaves 2 T V cubic inches 292 deg. 
By the globe B, with green water and 17 grs. of raw filk 2 t V - — 307 
Another globe (C), filled with green water alone, was expofed 
at the fame time ; but it was broken by an accident before the 
experiment was completed. 
The two globes (A and B) with their contents, being again 
expofed from Tuefday noon till Thurfday evening, yielded air 
as follows. 
Quantity, Quality. 
The globe A, with the peach leaves 4-iVff cubic inches 344 degrees 
The globe B, with raw lilk » — 4^ — — 350 
N. B. The weather on Tuefday and Wednefday was cold, 
with very little funfhine ; but Thurfday was a very fine warm 
day, when the greateft part of the air was produced. This 
air was removed and proved on Friday morning the 15th Sep- 
tember^ 
Perhaps all the appearances above deferibed might be fatif- 
fa&orily accounted for, by fuppoflng the air produced in the 
different experiments to have been generated in the mafs of 
water by the green matter ; and that the leaves, the filk, &c. 
did no more than ajjiji it in making its efcape , by affording it a 
convenient furface to which it could attach itfelf, in order to 
its colle&ing itfelf together, and taking upon itfelf its elaftic 
form.
