Dear Mr. Crookes¹

Many thanks for the copy of your papers on Psychic Force.² The 2nd. is most admirable; both in the tone & spirit with which it answers criticisms, & the irresistible force of its new facts. Spiritualists are greatly indebted to you for furnishing them, in your self registered experiments, with a final [2] answer to the "biologising" objection, recently put forth by Balfour Stewart³ & still more recently made the subject of a book⁴ supposed to crush spiritualism, by Mr. Zereffi.⁵

I hope you may soon be able to exhibit these self registering experiments in the theatre of the Royal Institution.

Yours very faithfully | Alfred R. Wallace [signature]
