58 Vegetable Staticks. 



out prejudice, a fome thing greater heat 

 than this, I have pitched upon the heat in 

 which melted wax fwimming on hot water 

 firfl begins to coagulate ; for fince a greater 

 heat than this will diflblve the wax, which 

 is a vegetable fubftance, this may therefore 

 well be fixed as the utmoft boundary of ve- 

 getation, on the warm fide ; 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 /pace I divided into 100 degrees 

 on all the Thermometers, beginning to num- 

 ber from the freezing point. Sixty-four of 

 thefe degrees are nearly equal to the heat of 

 the blood of animals ; which I found by 

 the rule given in the Philofophical Tranf- 

 aftions, Vol. II. p. 1. of Mr. Motte's Abridg- 

 ment, which is fuppofed to be Sir Ifaac 

 Neictons eflimate 5 viz. by placing one of 

 the Thermometers in water heated to the 

 greater!: degree that I could bear my hand 

 in it ftirring it about : And which I wa s 

 further aflured 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 14.27 to 33.
