ANIMALS AND VEGETABLES. 



S 



A third refemblance yifesfrom the follovvin 

 fadt: Some animals are propagated in the fame 

 manner and by the fame means, as vege'ables. 

 The multiplication of the vine-fretter, (puceron)^ 

 which is effected without copulation, isfimilarto 

 that of plants by feed ; and the multiplication of 

 the polypus by cuttings refembles that of plants 

 by flips. 



We may, therefore, conclude, with more cer- 

 tainty, that animals and vegetables are beings 

 of the fame order, and that Nature pafTes from 

 the one to the other by imperceptible degrees; 

 fince the properties in which they refemble each 

 other are univerfal and efTential, while thofe by 

 which they are diflinguifhed are limited and 

 partial. 



Let us next compare animals and vegetables 

 in different points of view ; for example, with 

 regard to number, lituation, magnitude, figure, 

 &c. from which new indudions will arife. 



Animals exceed plants in the number of fpe- 

 cies. In the clafs of infers alone, there are^ 

 perhaps, a greater number of fpecies, than of the 

 whole fpecies of plants on the face of the earth. 

 Animals differ from each other much more than 

 plants: It is the great fimilarity of plants that 

 has given rife to the difficulty of diftinguifhing 

 and arranging them, and to the variety of bo- 

 tanical fyftems, which are much more numerous 

 than thofe of zoology.
