There is in the chemist a form of thought by which all ideas become visible in the mind as strains of an imagined piece of music. This form of thought is developed in Faraday in the highest degree, whence it arises that to one who is not acquainted with this method of thinking, his scientific works seem barren and dry, and merely a series of researches strung together, while his oral discourse when he teaches or explains is intellectual, elegant, and of wonderful clearness.

A fact acquires its true and full value only through the idea which is developed from it.

But it must not be forgotten that ... glass and porcelain were manufactured, stuffs dyed and metals separated from their ores by mere empirical processes of art, and without the guidance of correct scientific principles.

From one sublime genius-NEWTON-more light has proceeded than the labour of a thousand years preceding had been able to produce.

The loveliest theories are being overthrown by these damned experiments; it's no fun being a chemist anymore.

A time will come, when fields will be manured with a solution of glass (silicate of potash), with the ashes of burnt straw, and with the salts of phosphoric acid, prepared in chemical manufactories, exactly as at present medicines are given for fever and goitre.

In this apparatus is nothing new but its simplicity and thorough trustworthiness. On his revolutionary method of organic analysis.
