V. THE SEED. 



I must once more desire the reader to take notice that, 

 tinder the four sections already defined, the morphology of 

 the plant is to be considered as complete, and that we are now 

 only to examine and name, farther, its product ; and that not 

 BO much as the germ of its own future descendant flower, but 

 as a separate substance which it is appointed to form, partly 

 to its own detriment, for the sake of higher creatures. This 

 product consists essentially of two parts : the Seed and its 

 Husk.

I. THE SEED. Defined 152 



It consists, in its perfect form, of three parts 153 



These three parts are not yet determinately named in the 

 text : hut I give now the names which will be usually at- 

 tached to them. 



A. The Sacque.The Outside skin of a seed 152 



B. TJie Nutrine. A word which I coin, for general applicabil- 



ity, whether to the farina of corn, the substance of a nut, 



or the parts that become the first leaves in a bean 152 



C. The Germ. The origin of the root 152 



II. THE HUSK. Defined 153 



Consists, like the seed when in perfect form, of three 

 parts. 



A. TJie Skin. The outer envelope of all the seed structures . . 153 



B. The Rind. The central body of the Husk 153-162 



C. The Shell. Not always shelly, yet best described by this 



general term ; and becoming a shell, o called, in nuts, 

 peaches, dates, and other such kernel-fruits 153 



The products of the Seed and Husk of Plants, for the use 

 of animals, are practically to be massed under the three heads 

 of BREAD, OIL, and FRUIT. But the substance of which bread 

 is made is more accurately described as Farina ; and the
