Vegetable Staiicks. 
out prejudice, a fomething greater Heat 
than this, I have pitched upon the heat in 
which melted wax fwimming on hot water 
firft begins to coagulate $ for ftnce a greater 
heat than this will diffolve the wax, which 
is a vegetable fubftance, this may therefore 
well be fixed as the utmoft boundary of ve- 
getation, on the warm fide 5 beyond which 
plants will rather fade than vegetate, fuch 
degree of heat feparating and difperfing, in- 
ftead of congregating, and uniting the nu- 
tritive particles. 
This fpace I divided into a 100 degrees 
on all the Thermometers , beginning to num- 
ber from the freezing point. Sixty four of 
thefe degrees is nearly equal to the heat of 
the blood of animals 5 which I found by 
the rule given in the Thilofophical Tranf- 
actions ,Vol.II. p, 1. of bAr.Motte’s Abridg- 
ment, which is fuppofed to be Sir Ifaac 
Newton's efiimate, viz. by placing one of 
the Thermometers in water heated to the 
greatefl: degree that I could bear my hand 
in it ftirring it about: And which I was 
further affured of, by placing the ball of my 
Thermometer in the flowing blood of an ex- 
piring Ox. The heat of the blood to that 
of boiling water is as 14 4- A to 3 3®
