Exp. I. In two of tliefe veflels I put as much of the conferva 
rivularis (a water plant, clafled by linn*us amongft the crypto - 
garni a ) as was fufficient to take up the fpace of about an inch 
fquare. 
Exp. IT. In the two next veflels I fufpended by threads tied to 
bits of cork, fome pieces of woollen and fdk cloth ot different 
colours, as white, Icarlet, green, and brown, having previoully 
wetted them in fome boiled water, on purpofe to free them 
from all air. 
Exp. III. In the two remaining veflels I placed nothing at all. 
Exp. IV. In another veflel of the fame form and fize I put 
fome of the conferva rivularis , and filled it with pump water. 
All thefe globular veflels were inverted, with their orifices 
immerfed in veflels filled with quickfiiver, for the purpofe of 
preventing effectually any communication between the contents 
of the veflels and the atmofphere. 
Refult of experiment I. The firfl: two days neither of 
the veflels contained any air, and even the lmall quantity 
of air, which here and there adhered in the form of a bub- 
ble to the fibres of the vegetable w r hen it was (hut up in 
the veflel, had entirely difappeared. The third day, in the 
morning, fome air bubbles began to rile from every pait of tbs 
conferva in both glafles ; and in the afternoon of the fame day, 
a great quantity of air bubbles rofe continually from it. I took 
at that time the vegetable out of one of thefe veflels. I plunged 
a wax taper, juft extinguilhed, into the orifice of this veflel, on 
purpofe to fee whether the air, already extricated from the con- 
ferva, was dephlogifticated or not. The wax taper took flame 
immediately with an uncommon fplendour. After this I 
poured the half of the water from the globular veflel dnto a 
common bottle, and corked it. I inverted this bottle afterwards
