nation from the currents of air, which it mufl now continue 

 perpetually to refpire to the end of its life ; as it now quits the 

 liquid element, in which it was produced, and like the tadpole, 

 when it changes into a frog, becomes an aerial animal. 



9. As tlu habitable parts of the earth have been, and con- 

 tinue to be, perpetually increafing by the produftion of fea- 

 fliell-s and corallines, and by the recrements of other animals, 

 and vegetables ; (o from the beginning of the exigence of this 

 terraqueous globe, the animals, which inhabit it, have conftant- 

 ly improved, and are (till in a date of progreflive improvement. 



This idea of the gradual generation of all things feems to 

 have been as familiar to the ancient philofophers as to the mod- 

 ern ones.; and to have given rife to the beautiful hieroglyphic 

 figure of the wgorav mv, or fir ft great eg^ y produced by night, 

 that is, whofe origin is involved in obfeurity, and animated by

VIII. i . Since the former publication of the preceding Sec- 

 tion on Generation, I have been induced in my treatife on Phyt- 

 ologia, to give more attention to the lateral or folitary genera- 

 tion of vegetables in the production of their buds, hoping from 

 thence to throw fome light on their fexual generation in the pro- 

 duction of feeds ; and in coniequence on the propogation of 

 more perfect animals, which I ihall here relate, believing that 

 it may intereft the philofophical reader, obferving only, that by 

 the vegetable facls here attended to, I am now induced to be- 

 lieve, that the embryons of complicate animal and vegetable 

 bodies are not formed from a fingle filament as above delivered ; 

 but that their ftructure commences in many parts at the fame 

 time, though it is probable, that the moft fnnple or firil exordi- 

 um of animation was begun by a fingle filament, and continues 

 to do fo in the fpontaneous production of the fmalleft micro- 

 fcopic animals, which do not appear to have been generated 

 by other animalcula fimilar to themfelves, as further fpoken of 

 in No. 11. 5. of this Section. 



1. It is (hewn at large in the work above mentioned, that 

 every bud of a tree is an individual vegetable, and confifts of the 

 plumula or leaf at its fummit, of a long caudex extending from 

 this fummit down wands to the earth, forming a filament of the 

 bark, and laftly of radicles beneath the foil : it is alfo fhewn, 

 that every bud poflelTes the power of germination or reproduc- 

 , not onlv in the axilla of the leaf, which is moft common, 



but
