All Organs Of An Animal Form A

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.

If They [enlightened Men] Take Any Interest In Examining, In The Infancy Of Our Species, The Almost Obliterated Traces Of So Many Nations That Have Become Extinct, They Will Doubtless Take A Similar Interest In Collecting, Amidst The Darkness Which Covers The Infancy Of The Globe, The Traces Of Those Revolutions Which Took Place Anterior To The Existence Of All Nations.

To Spread Healthy Ideas Among Even The Lowest Classes Of People, To Remove Men From The Influence Of Prejudice And Passion, To Make Reason The Arbiter And Supreme Guide Of Public Opinion; That Is The Essential Goal Of The Sciences; That Is How Science Will Contribute To The Advancement Of Civilization, And That Is What Deserves Protection Of Governments Who Want To Insure The Stability Of Their Power.

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.
