I. I. The feeds of vegetables are a fexual offspring correfponding 

 with the eg2;s of animals, and contain, like thenfi, not only the rudi- 

 ment of the new organization, but alfo a quantity of aliment laid up 

 for its early nouriflimcnt 



Th 



of birds contain two kinds of album 



h 



fs vifcid than the other, which is firft confumed, and the yolk or 



m, which is drawn up into the bowels of the chick 



fion from the fh 



and ferves it for 



(hment a day 



wo 



till it can learn to fele61; and digeft grains or infedls. In like manner 

 many feeds are furnifhed with two kinds of nourifhment, the mucl- 

 lao-inous or oily meal of the feed-lobes, ahd the faccharine or acefcent 



pulp of the fruit, as in pears, plums, cucumbers, which fupply nu- 

 triment to the embryon plant, till it is able to ftrike into the earth fuf 

 ficient roots for the purpofe of abforbing its nutritious juices. 



The fpawn of fifh, and of frogs, and of infers, as of fnailsand bees, 

 which are almoft as innumerable as the feeds of plants, and are in th( 

 fame manner excited into life by the warmth of the fun, are analo 

 (Tous to thofe feeds, I believe, which are not furrounded with ffuit, 



but one kind of nourifhment for the embryon 

 plant, as grains of corn, and legumes ; but perhaps thefe have not 

 yet been fufficiently attended to by philofophers. 



rhefe eggs of animals and feeds of vegetables are produced by the 



ins ; the former fupplying the fpeck
