I happen to have discovered a direct relation between magnetism and light, also electricity and light, and the field it opens is so large and I think rich.

Speculations? I have none. I am resting on certainties.

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.

Magnetic lines of force convey a far better and purer idea than the phrase magnetic current or magnetic flood: it avoids the assumption of a current or of two currents and also of fluids or a fluid, yet conveys a full and useful pictorial idea to the mind.

Nature is our kindest friend and best critic in experimental science if we only allow her intimations to fall unbiased on our minds.

I have far more confidence in the one man who works mentally and bodily at a matter than in the six who merely talk about it.
