 Will it also be without end? The species itself, is it indestructible, or does it pass away like its individuals? Has man always been what he now is; or has he, before he arrived at the state in which we see him, been obliged to pass under an infinity of successive developements? Can man at last flatter himself with having arrived at a fixed being, or must the human species again change? If man is the production of Nature, it will perhaps be asked, Is this Nature competent to the production of new beings, to make the old species disappear? Adopting this supposition, it may be inquired, why Nature does not produce under our own eyes new beings&mdash;new species?

It would appear on reviewing these questions, to be perfectly indifferent, as to the stability of the argument we have used, which side was taken; that, for want of experience, hypothesis must settle a curiosity that always endeavours to spring forward beyond the boundaries prescribed to our mind. This granted, the contemplator of Nature will say, that he sees no contradiction, in supposing the human species, such as it is at the present day, was either produced in the course of time, or from all eternity: he will not perceive any advantage that can arise from supposing that it has arrived by different stages, or successive developements, to that state in which it is actually found. Matter is eternal, it is necessary, but its forms are evanescent and contingent. It may be asked of man, is he any thing more than matter combined, of which the former varies every instant?

Notwithstanding, some reflections seem to favor the supposition, to render more probable the hy
