No One Nor Anything Can Silence Me.

When The Elements Are Arranged In Vertical Columns According To Increasing Atomic Weight, So That The Horizontal Lines Contain Analogous Elements Again According To Increasing Atomic Weight, An Arrangement Results From Which Several General Conclusions May Be Drawn.

We Must Expect The Discovery Of Many As Yet Unknown Elements-for Example, Elements Analogous To Aluminum And Silicon- Whose Atomic Weight Would Be Between 65 And 75.

The Elements, If Arranged According To Their Atomic Weights, Exhibit An Apparent Periodicity Of Properties.

There Exists Everywhere A Medium In Things, Determined By Equilibrium.

There Is Nothing In This World That I Fear To Say.
