Whether he or another was its exponent, he appeared to take equal
delight in science. A good experiment would make him almost dance with
delight. In November, 1850, he wrote to me thus:--'I hope some day to
take up the point respecting the magnetism of associated particles.
In the meantime I rejoice at every addition to the facts and reasoning
connected with the subject. When science is a republic, then it gains:
and though I am no republican in other matters, I am in that.' All his
letters illustrate this catholicity of feeling. Ten years ago, when
going down to Brighton, he carried with him a little paper I had just
completed, and afterwards wrote to me. His letter is a mere sample of
the sympathy which he always showed to me and my work.

'Brighton, December 9, 1857.

'My Dear Tyndall,--I cannot resist the pleasure of saying how very much
I have enjoyed your paper. Every part has given me delight. It goes on
from point to point beautifully. You will find many pencil marks, for I
made them as I read. I let them stand, for though many of them receive
their answer as the story proceeds, yet they show how the wording
impresses a mind fresh to the subject, and perhaps here and there you
may like to alter it slightly, if you wish the full idea, i.e., not an
inaccurate one, to be suggested at first; and yet after all I believe
it is not your exposition, but the natural jumping to a conclusion that
affects or has affected my pencil.

'We return on Friday, when I will return you the paper.

'Ever truly yours,

'M. Faraday.'

The third letter will come in its proper place towards the end.

While once conversing with Faraday on science, in its relations to
commerce and litigation, he said to me, that at a certain period of his
career, he was forced definitely to ask himself, and finally to decide
whether he should make wealth or science the pursuit of his life. He
could not serve both masters, and he was therefore compelled to choose
between them. After the discovery of magneto-electricity his fame was
so noised abroad, that the commercial world would hardly have considered
any remuneration too high for the aid of abilities like his. Even before
he became so famous, he had done a little 'professional business.' This
was the phrase he applied to his purely commercial work. His friend,
Richard Phillips, for example, had induced him to undertake a number of
analyses, which produced, in the year 1830, an addition to his
