Hence the feeds of plants, which are liable to produce too vigorou 

 roots, and thence have not time to ripen their fruits in the (hort fum 

 mers of this climate, or which fill our hot-beds with too luxuriant fo

icilaorinous. or farinaceo 



or four years ; by which part of the mucilaginous, or 



oily matter of the cotyledons becomes injured or decayed, and the new 



plant grows lefs luxuriantly. 



Another fource of nutriment for the feminal embryon of many 

 plants exifts in the fruit, which envelopes the ftone or feed-veffel, 

 after the growing fetus has burft its confinement, and fo far re- 

 fembles the yolk of the egg, which becomes a nutriment to the chick, 

 after it has confumed the white, and eloped from its fh
