'&11 fruiU and seeds have this in common, fhey en- 

 -close under one or more coverings the gerra of the 

 future plants. Some l.ave only such coverings as im- 

 , mediately infold the germ, v.hose outside is of the 

 strongest contexture; and among these, there are 

 some that are provided \vilh wings, tufts, or plumes of 

 feothers, by -means of which they are conveyed in the 

 air or water, by which ihey are transported and sown 

 hi different parts. Others are better clothed, being 

 lodged in sheaths or pods, enclosed in a kind of box, 

 having one or more partitions. A third sort, under a 

 most delicious fruit, which is rendered still more -agree-

 others are enclosed in shells, which are either armed 

 \dth prickles, abound with a bitter juice, or adorned 

 with fine hair. 



The outside of fruits and seeds do not afford less

9- The inside of plants' is composed of four orders of 

 vessels, viz. the Ligneous fires, utriculi, or little lags, 

 the proper vases, and the trachea, or air vessels. 



The ligneous fibres are very small channels deposited 

 according to the length of the plant, and consist of 

 little pipes placed near each other. Sometimes these 

 vessels are parallel, and at others are separated, leaving 

 between them intervals, or oblong spaces. 



These spaces are filled by the utruuli, a kind of 

 membranous bladders, horizontally disposed, and which 

 communicate with each other. 



The proper vases "are a kind of ligneous fibres which 

 principally differ from the rest by their juice, which is 

 of a deeper colour, or thicker.
