6 Vegetable Static fa. 



each; by numbering of which I had the fur- 

 face of the leaves in fquare inches, which 

 multiplied by the number of the leaves in 

 the correfponding parcels, gave me the area 

 pf all the leaves ; by which means I found 

 the furfaceofthewholeplant, above ground, 

 to be equal to 5616 fquare inches, or 39 

 fquare ica. 



I dug up another Sun flower, nearly of 

 the fame foe, which had eight main roots, 

 reaching fifteen inches deep and fideways 

 from the item : It had befides a very thick 

 bufn of lateral roots, from the eight main 

 roots, which extended every way in a He- 

 mifphere, about nine inches from the ftem 

 and main roots. 



In order to get an eftimate of the length 

 of all the roots, I took one of the main roots, 

 with its laterals, andmeafured and weighed 

 them,and then weighed the other feven roots, 

 with their laterals, by which means I found 

 the fum of the length of all the roots to be 

 no lefsthan 1448 feet. 



And fuppofing the periphery of thefe roots 

 $t a medium, to be 44 of an inch, then their 

 furface will be 22 8 6 fquare inches, or 15. $
