‘perature of the atmofphere, and confequently 
‘iniall bodies furrounded by it. I fhall now en- 
deavour to prove experimentally the truth of 
what I formerly advanced as a probable conjec- 
ture, by fhewing that the vegetative principle 
in feeds is deftroyed by the putrefactive fermen- 
tation ; and. that. the. commencement of. this 
procefs depends on,the changes in queftion being 
accelerated or retarded, as the temperature in- 
creafes or diminifhes. 
Experiment, X.- Jan. gift. 1794.— Three 
ounces of .dry, peas;were- put.to foak in rain 
water: February 2d. four drams ‘of the peas, 
which had now: been fteeped: forty-eight hours, 
were removed into a phial, which, was then filled 
with water, and inverted in an.earthen jar of 
the fame: that part of the bottle which was out 
of the veffel being fcreened fromthe light by a 
_cafe of brown paper. It was then placed, ina 
window looking to the North, (where a thermo- 
meter was hanging) clofe ‘to the. veffel con- 
taining the water, in which the remaining part 
of. the three ounces was immerfed. 
At the fame time, I placed two drams of the 
peas, thus foaked, in a phial; and removed 
them to a much warmer room, where they foon 
vegetated. The fame was repeated, with equal 
fuccefs, at the end of every forty- eight, hours, 
to the eighth.
