 supply of Asiatic animals to New Holland, ad- 

 mit a second revolution, which destroyed Asia,

 observe them in New Holland, their second 

 country, would be equally at a loss to know

I now proceed to apply this manner of reason-

Proofs that there are no Fossil Human Bones. 



It is certain that no human bones have yet

When I assert that human bones have never 

 been found among fossil organic remains, (I must
