But, lo ! the day before the sitting was to have been held, Fara¬ day demanded a programme of what was to take place ! In a letter dated June 14, 1861,, he says, “It would be a con- descensio?i on my part to pay any more attention to them [the occult phenomena] now.” He asks, “Does Mr. Home wish me to go? Is he willing to investigate as a philosopher, and, as such, to have no concealments, no darkness? . . . Does he make himself x-esponsible for the effects, and identify himself more or less with their cause? Would he be glad if their delusive charac¬ ter were established and exposed ; and would he gladly help to expose it, or would he be annoyed and personally offended? Does he consider the effects natural or supernatural ? If natural, what are the laws which govern them? or does he think they are not subject to laws?

If the effects are miracles, or the work of spirits, does he admit the utterly contemptible character, both of them and their results, up to the present time, in respect either of yielding information or instruction, or supplying any force or action of the least value to mankind?” Such was the spirit in which the great scientist approached the subject. And Mr. John Tyndall, the eulogist of Faraday, and hardly his inferior as a man of science, makes the follow¬ ing announcement, under date of May 8, 1868 : “ I hold myself in readiness to witness and investigate, in the spirit of the forego¬ ing letter, such phenomena as Mr. Home may wish to reveal to me during the month of June.” Mr. Tyndall, echoing Faraday, calls upon Mr. Home, as pre¬ liminary to the “condescension” of an investigation by Mr. Tyndall, to “ admit the utterly contemptible character of the manifestations and their results ” ! In his reply to Mr. Tyndall, Mr. Home writes, “ I would ask
