10. A plant does not only multiply by seeds and 

 buds ; it is likewise propagated by suckers and sprigs. 

 It may also be multiplied by slips and by engrafting. 



A tree sends forth small buds from various parts of 

 its surface : these buds increase in bulk, they open and 

 disclose the shoat, which extends itself every day. 

 While it is expanding itself, other still smaller sprigs 

 shoot from it : these, in their turn, are succeeded by 

 lesser ones, all of which are so many trees in miniature; 

 and tlr* nourishment received by one of these sprigs is 

 communicated to the whole plant. 



When it has attained to a certain size, and is sepa- 

 rated from the trunk either by nature or otherwise, 

 these shoots sustain themselves and become so many- 

 distinct trees. Being cut into pieces according to their 

 width, or even their length, these shoots will grow 

 again of themselves and will become as many trees as 

 they were made slips of. The leaves themselves, when 

 separated from their shoots, may afford so many com- 

 plete plants. Being fastened closely to each other, or. 

 inserted in one another, several of these shoots, whe- 

 ther taken from the same or from different individuals, 

 will unite together in so intimate a manner, that they 

 wii! receive reciprocal nourishment, and form one indi- 

 vidual whole. 



The animal is not only propagated by eggs and 

 living young, but likewise by shoots. It may also be 

 multiplied by slips and ingraftings. A polypus send* 

 forth little luds from different parts of his body. These 

 buds grow big and lengthen insensibly : every one of 

 them is a young shoot : while it is unfolding itself, 

 there springs from it other smaller shoots : these, in 

 their turn, produce smaller still. AH these shoots are 

 so many little polypuses, and the nourishment one of 

 these polypuses receives, is communicated to their 

 whole number, When they have arrived to a certain 

 size, -they separate themselves from the trunk, and be- 

 come so many individuals.
