3 jo Of Vegetation . 
aparticular defcription of the ftrudure of the 
parts of vegetables, which has already been ac- 
curately done by Dr. Grew and Malpighi . 
We fee by Experiment 5 < 5 , 57, 58, on 
diftilled Wheat, Peafe and Muftard-feed, 
what a wonderful provifion nature has made, 
that the Seeds of Plants fhould be well ftored 
with very a&ive principles, which principles 
are there compared together by him, who 
curioully adapts all things to the purpofes 
for which they are intended, with fuch a 
juft degree of cohefion as retains them in 
that ftate till the proper feafon of germi- 
nation j for if they were of a more lax con- 
futation, they would too foon diffolve like 
the other tender annual parts of plants : And 
if they were more firmly connefted, as in 
the heart of Oak, they muft neceffarily have 
been many years in germinating, tho’ fup- 
pled with moifture and warmth. 
When a Seed is fown in the ground, in 
a few days it imbibes fo much moifture, as 
to fwell with very great force; as we fee 
in the Experiment on Peafe in an iron po t 9 
this forcible fwelling of the lobes of the 
Seed ar 7 ar (Fig. 46.) docs probably pro- 
trude moifture and nourifhment from the 
capillary veflels rr 7 which are called the 
Seed
