fcen that the cover held faft totheBolrheadno longer, I made no 
doubt of the Corants having produced Air enough to life up the 
faid great Glafs,and to form in theTurpentin the bubles Itod feen. 
I was confirmed in thisthoughr,when I found by ihefmell that they 
had fermented. They were yet good, except fome that had loft 
almoft all their tafle, and all their acidity. 
The fame thing hapn'd to me with a very fmall Receiver , that 
could hold no more than one Cherry (s>^ that kind we call Big^r- 
reaux) and one red Cor ant, Thefe fruits yielded alfo Air enough 
to lift up their Receiver [even days after they had been included 
therein ; And havingreirteratedthis Experiment, I found the fame 
fuccefs ; on^y this fecond time the Receiver was not lifted up till 
the eleventh ddiy.. This effeft is ra^herxo be: afcribed to the Cher- 
ry than the Corant *, becaufelhave kept Corants to the number of 
elevemn a fmall Glafs, and they did not raife it up. Whence it fol- 
lows, that thefe BtgarreHx y'l^ld much more Air than Acid fruit. 
Another time I included fome of the fame kind of Cherries a 
whole great Glafj fall, and found, that from theyj'^i?;;^ day they had 
yielded Air enough to lift up the cover. I took away part of the 
Cherries, and included the reft again. This fecond time they did 
not raife the Glafs till the eighth day. The Cherries looked fair, 
but they had loft much of their tafte, and afterwards they were 
fpoiled in lefa than an hour. 
I did alfo one day include three Pears^o? that fort we call Rouf- 
fekt^'im like figured Glafs, which could hold no more. They lifted 
iiptheGlaf>ai: the end of ^z/^ days, and they were not changed, on- 
ly one of them was a little fofter. 
Another time I put a Feach in fuch a Glafs emptied of Air, with 
a Gage to it 5 and I found, that the firft^x hours the Quickfilver 
in the Gage was rifen about an inch. Yet it was not till the thir- 
teenth day that the Glafs was lifted up ; and the Peach appeared to 
have kept very v^ell till then ; but after that, it rotted in a very lit- 
tle time. 
I did once put up fome -Br^^^ with a Gage ; but I found not that 
forihe fpace of a whole month it had yielded any Air ^ fo that I 
took it out, and found ityetgood ; only it had a little tafte of 
muftinefs, which yet appeared not at all to the Eye , and whereof 
thecaufemay beadfcribed to that little Air that might reft in the 
Receiver.
