 regarded as a corollary from the first, the truth 

 or falsehood of which is a matter of evidence. 

 Most persons imagine that the arguments in 

 favour of it are overwhelming ; but to some few 

 minds, and these, it must be confessed, intellects

 minds, that of the famous naturalist Lamarck, 

 who possessed a greater acquaintance with the 

 lower forms of life than any man of his day, 

 Cuvier not excepted, and was a good botanist to 

 boot, occupies a prominent place. 



Two facts appear to have strongly affected the
