' Upon the whole/ the Do6lor concludes, ^ there are few

The ingenious Charles Bonnett endeavors to {how, thai 

 the parts of all organifed bodies are contained, in miniature, 

 in germs or buds ; that thefe germs, when placed in proper 

 fituations, gradually unfold and increafe in magnitude ; that 

 the various members of animals and vegetables are expand-* 

 ed, both longitudinally and laterally, by food adapted to 

 their refpe<Stive natures j and that every germ actually in- 

 cludes the rudiments of the whole animals or vegetables 

 which are to proceed from it during all fucceffive gene- 

 rations. 



With regard to vegetables, it is true, that the feed firfl: 

 produces a fmall tree, which it contained in miniature with-* 

 in its lobes. At the top of this fmall tree a bud or germ is 

 formed, which contains the Ihoot or tree tliat is to fpring 

 next feafon. In the fame manner, the fmall tree of the 

 fecond year produces a bud which includes a tree for the 

 third year ; and this procefs uniformly goes on as long as 

 the tree continues to vegetate. At the extremity of each
