their branches together and extend tkeir boughs and 

 roots to the extremity of the world. 



The outside and inside of the earth, mountains and 

 rallies, barren and fertile places, countries undiscovered 

 and hid in dark obscurity, the regions of the north and 

 south, rivulets, rivers, ponds, lakes, and seas, have their 

 vegetables and animals. 



Many species of plants and animals seem to thrive 

 alike in different climates. Other species are amphibious, 

 and live as well out of the water as in it. The bulrush 

 midfrog flourish in meadows, and at the bottom of 

 ponds. Others are parasites, and are nourished by the 

 juices they extract from different species. Such are the 

 misletoe and the louse. 



Lastly, Some parasite species supply their necessities, 

 in their turn, from other parasites. The misletoe lias 

 his liverworts, and certain lice have their lice. 



15. There are upwards of twenty thousand species of 

 plants known to us, and new discoveries of them are 

 made every day. A microscopical botany has extended 

 the dominions of the ancient. Mosses, mushrooms, liver- 

 worts, whose families are innumerable, now take place 

 amongst vegetables, and present the curious with flowers 

 and seeds which before they were unacquainted with. 

 The microscope discovers plants to our view, where we 

 never suspected them. Free-stone is often covered with 

 spots of different colours, commonly brown or blackish. 

 Glass, notwithstanding its fine polish, is not exempt 

 from such spots. We observe hoariness on almost all 

 bodies. These spots and this hoariness are found to be 

 gardens, meadows, and forests, in miniature, whose 

 plants that are infinitely small, afford us nevertheless 

 some prospect of their flowers and seeds. 



But although vegetables are very numerous in their 

 species, yet they are much less so than animals. Every 

 species of plant has not only its particular species of 

 animals, but there are many species of plants which 

 nourish several species of animals. The oak alone
