The Observer Listens To Nature:

My Object Will Be, First, To Show By What Connections The History Of The Fossil Bones Of Land Animals Is Linked To The Theory Of The Earth And Why They Have A Particular Importance In This Respect.

All Organs Of An Animal Form A Single System, The Parts Of Which Hang Together, And Act And Re-act Upon One Another; And No Modifications Can Appear In One Part Without Bringing About Corresponding Modifications In All The Rest.

The Works Which This Man [joseph Banks] Leaves Behind Him Occupy A Few Pages Only; Their Importance Is Not Greatly Superior To Their Extent; And Yet His Name Will Shine Out With Lustre In The History Of The Sciences.

It Is To Them [fossils] Alone That We Owe The Commencement Of Even A Theory Of The Earth ... By Them We Are Enabled To Ascertain, With The Utmost Certainty, That Our Earth Has Not Always Been Covered Over By The Same External Crust, Because We Are Thoroughly Assured That The Organized Bodies To Which These Fossil Remains Belong Must Have Lived Upon The Surface Before They Came To Be Buried, As They Now Are, At A Great Depth.

It Has Been Long Considered Possible To Explain The More Ancient Revolutions On... The Earth Surface By Means Of These Still Existing Causes; In The Same Manner As It Is Found Easy To Explain Past Events In Political History, By An Acquaintance With The Passions And Intrigues Of The Present Day. But We Shall Presently See That Unfortunately This Is Not The Case In Physical History:-the Thread Of Operation Is Here Broken, The March Of Nature Is Changed, And None Of The Agents That She Now Employs Were Sufficient For The Production Of Her Ancient Works.
