I Cannot Persuade Myself That A Beneficent

Although I Am Fully Convinced Of The Truth Of The Views Given In This Volume Under The Form Of An Abstract, I By No Means Expect To Convince Experienced Naturalists Whose Minds Are Stocked With A Multitude Of Facts All Viewed, During A Long Course Of Years, From A Point Of View Directly Opposite To Mine... I Look With Confidence To The Future, To Young And Rising Naturalists, Who Will Be Able To View Both Sides Of The Question With Impartiality.

It May Be Conceit, But I Believe The Subject Will Interest The Public, And I Am Sure That The Views Are Original.

...he Who Remains Passive When Over-whelmed With Grief Loses His Best Chance Of Recovering His Elasticity Of Mind.

It Is Really Laughable To See What Different Ideas Are Prominent In Various Naturalists' Minds, When They Speak Of 'species'; In Some, Resemblance Is Everything And Descent Of Little Weight-in Some, Resemblance Seems To Go For Nothing, And Creation The Reigning Idea-in Some, Descent Is The Key,-in Some, Sterility An Unfailing Test, With Others It Is Not Worth A Farthing. It All Comes, I Believe, From Trying To Define The Undefinable.

The Willing Horse Is Always Overworked.
