A Man In Twenty-four Hours Converts As Much As Seven Ounces Of Carbon Into Carbonic Acid; A Milch Cow Will Convert Seventy Ounces, And A Horse Seventy-nine Ounces, Solely By The Act Of Respiration. That Is, The Horse In Twenty-four Hours Burns Seventy-nine Ounces Of Charcoal, Or Carbon, In His Organs Of Respiration To Supply His Natural Warmth In That Time ..., Not In A Free State, But In A State Of Combination.

The World Little Knows How Many Of The Thoughts And Theories Which Have Passed Through The Mind Of A Scientific Investigator, Have Been Crushed In Silence And Secrecy By His Own Severe Criticism And Adverse Examination!

It Is The Great Beauty Of Our Science, Chemistry, That Advancement In It, Whether In A Degree Great Or Small, Instead Of Exhausting The Subjects Of Research, Opens The Doors To Further And More Abundant Knowledge, Overflowing With Beauty And Utility.

You Will Be Astonished When I Tell You What This Curious Play Of Carbon Amounts To. A Candle Will Burn Some Four, Five, Six, Or Seven Hours. What, Then, Must Be The Daily Amount Of Carbon Going Up Into The Air In The Way Of Carbonic Acid! ... Then What Becomes Of It? Wonderful Is It To Find That The Change Produced By Respiration ... Is The Very Life And Support Of Plants And Vegetables That Grow Upon The Surface Of The Earth.

I Have Long Held An Opinion, Almost Amounting To Conviction, In Common I Believe With Many Other Lovers Of Natural Knowledge, That The Various Forms Under Which The Forces Of Matter Are Made Manifest Have One Common Origin; Or, In Other Words, Are So Directly Related And Mutually Dependent, That They Are Convertible, As It Were, One Into Another, And Possess Equivalents Of Power In Their Action.
