Look at the unbroken & untilled ground in La Plata covered with European products; they have no near affinity to the indigenous; they are not American types which conquer the aborigines.

You will understand that for brevity I thus write dogmatically. ─

This doctrine is superfluous on theory of nat. selection, There is no reason why [5 words crossed] which implies no necessary tendency to progression. A monad if no deviation in its structure occurred profitable to it under its excessively simple conditions of life might remain unaltered for long before Silurian age to present day,─ I grant there will be a general tendency to advance in organisation; though in products fitted for very simple conditions it would be slight & slow. The secondary infusoria differ but little from the living.

The parent monad form might perfectly well survive unaltered & fitted for its simple conditions, whilst
