Languages Are True Analytical Methods.

Vegetation Is The Basic Instrument The Creator Uses To Set All Of Nature In Motion.

In Every Combustion There Is Disengagement Of The Matter Of Fire Or Of Light. A Body Can Burn Only In Pure Air [oxygen]. There Is No Destruction Or Decomposition Of Pure Air And The Increase In Weight Of The Body Burnt Is Exactly Equal To The Weight Of Air Destroyed Or Decomposed. The Body Burnt Changes Into An Acid By Addition Of The Substance That Increases Its Weight. Pure Air Is A Compound Of The Matter Of Fire Or Of Light With A Base. In Combustion The Burning Body Removes The Base, Which It Attracts More Strongly Than Does The Matter Of Heat, Which Appears As Flame, Heat And Light.

Imagination, On The Contrary, Which Is Ever Wandering Beyond The Bounds Of Truth, Joined To Self-love And That Self-confidence We Are So Apt To Indulge, Prompt Us To Draw Conclusions Which Are Not Immediately Derived From Facts.

The Whole Art Of Making Experiments In Chemistry Is Founded On The Principle: We Must Always Suppose An Exact Equality Or Equation Between The Principles Of The Body Examined And Those Of The Products Of Its Analysis.

We May Lay It Down As An Incontestible Axiom, That, In All The Operations Of Art And Nature, Nothing Is Created; An Equal Quantity Of Matter Exists Both Before And After The Experiment; The Quality And Quantity Of The Elements Remain Precisely The Same; And Nothing Takes Place Beyond Changes And Modifications In The Combination Of These Elements. Upon This Principle The Whole Art Of Performing Chemical Experiments Depends: We Must Always Suppose An Exact Equality Between The Elements Of The Body Examined And Those Of The Products Of Its Analysis.
