It Is Always Advisable To Perceive Clearly

I Have Just Finished My Sketch Of My Species Theory. If As I Believe That My Theory Is True & If It Be Accepted Even By One Competent Judge, It Will Be A Considerable Step In Science. I Therefore Write This, In Case Of My Sudden Death, As My Most Solemn & Last Request, Which I Am Sure You Will Consider The Same As If Legally Entered In My Will, That You Will Devote 400£ To Its Publication & Further Will Yourself, Or Through Hensleigh [wedgwood], Take Trouble In Promoting It.

But Just In Proportion As This Process Of Extermination Has Acted On An Enormous Scale, So Must The Number Of Intermediate Varieties, Which Have Formerly Existed, Be Truly Enormous. Why Then Is Not Every Geological Formation And Every Stratum Full Of Such Intermediate Links? Geology Assuredly Does Not Reveal Any Such Finely Graduated Organic Chain; And This, Perhaps, Is The Most Obvious And Serious Objection Which Can Be Urged Against The Theory. The Explanation Lies, As I Believe, In The Extreme Imperfection Of The Geological Record.

Thus We Have Given To Man A Pedigree Of Prodigious Length, But Not, It May Be Said, Of Noble Quality.
