6 Vegetable Statich . 
each j 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 
of all the leaves; by which means I found 
the furface of the whole plant, above ground^ 
to be equal to 5616 fquare inches, or 39 
fquare feet. 
I dug up another Sun flower, nearly of 
the fame ftze, which had eight main roots, 
reaching fifteen inches deep and fideways 
from the ftem : It had befides a very thick 
bufli 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, and meafured 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 lefs than 1448 feet. 
And fuppofing the periphery of thefe 
roots at a medium, to be 44 of an inch, 
then their furface will be 2286 fquare 
|nches, or i$ a 8 fquare feet; that is, e-
