 and Malpighi. 



We fee by Experiment 56, 57, 58, oa 

 diftilled Wheat, Peafe and Muftard feed, 

 what a wonderful provifion nature has made, 

 that the Seeds of Plants fliould be well ftored 

 with very a&ive principles, which princi- 

 ples are there compared together by him, 

 who curioufly adapts all things to the pur- 

 pofes for which they are intended, with 

 fuch a juft degree of cohefion as retains them 

 in that ftate till the proper feafon of ger- 

 mination 5 for if they were of a more lax 

 conftitution, they would too foon diflblve 

 like the other tender annual parts of plants : 

 And if they were more firmly conne&ed, a s 

 in the heart of Oak, they muft neceffariljr 

 have been many years in germinating, tho 8 

 fuppled 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 5 as we fee 

 in the Experiment on Peafe in an iron pot, 

 this forcible fwelling of the lobes of the 

 Seed ar,ar (Fig. 46.) does probably pro- 

 trude moifture and nourifhment from the 

 capillary veffels r r 7 which are called the 



Seed
