tween 38° and 48°, being commonly at 43°. 
The bottle remained full of water to the fixth ; 
-but the weather then became warmer (the ther- 
mometer ftanding at 46° or 48°), and two large 
‘bubbles of air were feen in the upper part of the 
glafs on the eighth. Thefe bubbles were fome- 
what larger on the tenth; and nearly two dram- 
meafures of air occupied the higher part of the 
inverted phial on the twelfth. 
The ufual quantity of peas, viz. two ce set 
placed in a dry bottle, on the evening of the 
tenth, fhewed hardly any figns of vegetation on 
the 13th. (thermometer from 46° to 48°) : but, 
on the 15th. fix, out of feventeen, had produced 
fprouts. An equal quantity of the peas which 
were yet lying in the water, was treated in the 
fame manner on the 12th; but they fhewed no 
figns of vegetating on the 17th. This is a proof 
that the peas yet in water had been {poiled by pu- 
trefaction ; the commencement of which was 
certainly indicated by the air extricated from 
thofe in the inverted bottle. The gas that was 
collected by the bottle, in the courfe of the 
experiment, confifted principally of carbonated 
bydrogene mixed with nearly one quarter of its 
bulk of carbonic acid gas. 
One circumftance feems worthy of notice, 
though not ftrictly applicable to the fubject of 
the prefent enquiry. The peas appeared to be 
faturated
