It will very likely be of no other service than collocating some facts; though I myself think I see my way approximately on the origin of species.

But, alas, how frequent, how almost universal it is in an author to persuade himself of the truth of his own dogmas.

My only hope is that I certainly see very many difficulties of gigantic stature.
If you can remember any cases of one introduced species beating out or prevailing over another, I should be most thankful to hear it.

I believe the common corn-poppy has been seen indigenous in Sicily.

I should like to know whether you suppose that seedlings of this wild plant would stand a contest with our own poppy; I should almost expect that our poppies were in some degree acclimatised and accustomed to our cornfields.
