[50] The accompanying diagram ([Fig. 20]) was not given by Faraday. It was pencilled by the author more than twenty years ago in the margin of his copy of Faraday’s “Experimental Researches,” vol. iii., p. 450, opposite this passage.
[51] The discourse was to have been delivered by Wheatstone himself, who, however, at the last moment, overcome by the shyness from which he suffered to an almost morbid degree, quitted the Institution, and left the delivery of the discourse to Faraday.

[53] It is right to add that what, according to the theory explained in the text, must be the correct explanation of the peculiar phenomena of magnetic induction depending on magnecrystallic properties was clearly stated in the form of a conjecture by Faraday in his twenty-second series in the following terms: “Or we might suppose that the crystal is a little more apt for magnetic induction, or a little less apt for diamagnetic induction, in the direction of the magnecrystallic axis than in other directions” (Sir William Thomson, Philosophical Magazine, 1851, or “Papers on Electrostatics and Magnetism,” p. 476).
[54] This is exactly Stokes’s theorem of “tubes” of force. S. P. T.

[56] Once again did Faraday intervene in Royal Society affairs at the crucial time when Lord Rosse was elected President in 1848. The following excerpts from the journals of Walter White show the cause:—
“November 25th.—There have been many secret conferences this week—much trimming and time-serving. Alas for human nature!”
“November 30th.—The eventful day, the ballot begun. Mr. Faraday made some remarks about the list.”
