Nothing tends so much to the advancement of knowledge as the application of a new instrument. The native intellectual powers of men in different times are not so much the causes of the different success of their labours, as the peculiar nature of the means and artificial resources in their possession.

Cuvier had even in his address & manner the character of a superior Man, much general power & eloquence in conversation & great variety of information on scientific as well as popular subjects. I should say of him that he is the most distinguished man of talents I have ever known on the continent: but I doubt if He be entitled to the appellation of a Man of Genius.

There may be beings, thinking beings, near or surrounding us, which we do not perceive, which we cannot imagine. We know very little; but, in my opinion, we know enough to hope for the immortality, the individual immortality, of the better part of man.

Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer.

Cavendish was a great Man with extraordinary singularities-His voice was squeaking his manner nervous He was afraid of strangers & seemed when embarrassed to articulate with difficulty-He wore the costume of our grandfathers. Was enormously rich but made no use of his wealth... He Cavendish lived latterly the life of a solitary, came to the Club dinner & to the Royal Society: but received nobody at his home. He was acute sagacious & profound & I think the most accomplished British Philosopher of his time.

James Watt was equally distinguished as a natural philosopher and chemist; his inventions demonstrate his profound knowledge of those sciences, and that peculiar characteristic of genius - the union of them for practical application.

It must always be borne in mind that the assumption of woman's social superiority lies at the root of these rules of conduct.
