ït would be a very great curiofity to colled a 

 great number of thefe oppofitions, and of thofe 

 analogies. They would lead us to a difcovery of 

 the plant, which is peculiarly adapted to each ani- 

 mal. Naturalifls have paid to thofe adaptations 

 no great degree of attention ; fuch of them as have 

 written the Hiftory of Birds, have clafled them 

 according to the feet, the bill, the noftrils. They 

 fometimes fpeak of the feafons of their appearance, 

 but fcarcely ever of the trees which they frequent. 

 Thofe only who, employed in making collections 

 of butterflies, are frequently under the neceffity of 

 looking for them in their ftate of nymph, or ca- 

 terpillar, have fometimes diftinguiflied thofe in- 

 fects by the names of the vegetables on which they 

 found them. Such are the caterpillars of the ti- 

 thymale, of the pine, of the elm, and fo on, which 

 they difcovered to be peculiarly appropriated to 

 îhefe vegetables. But there is not an animal ex- 

 ifting but what may be referred to it's own parti- 

 cular correfponding plant. 



We have divided plants into aerial, aquatic, and 

 terreftrial, as animals themfelves are divifible, and 

 we have found, in the two extreme dalles, unvary- 

 ing harmonies with their elements. They may be 

 farther divided into two clafles, into trees and 

 herbs, as animals likewife are into volatile and 

 quadrupeds. Nature does not affociate the two 



kingdoms
