The remaining chapter, dealing as it does with "Poltergeists and Mediums," takes us into the more dubious field of "physical phenomena"--spontaneous and experimental--and cases are discussed which lie outside the province of the psychologist,-- since they entrench more upon the domain of physics and biology. As such they have been treated and discussed by the majority of Continental savants. One word more regarding the famous medium, Eusapia Palladino, whom Mr. Bruce refers to in several passages in this Chapter, referring to her in a footnote on page 196, as "The discredited Eusapia Palladino, once the marvel of two continents." May I take this occasion to repeat here what I have often repeated in public and private, elsewhere? and that is, that I retain my unshaken belief, amounting to a conviction, in the genuineness of Eusapia's power, and that, despite the trickery which was undoubtedly discovered here--and which had also been discovered, I may add, more than twenty years before she ever came to this country--she yet possesses genuine, remarkable powers of a supernormal character, and this belief, I may say, is shared equally by all the continental investigators, who remain unaffected by the so-called American expose. A statement of their attitude is perhaps well summarized by Flournoy, in his Spiritism and Psychology (Chap. VII); while I have published the records of the American seances-- for those who may be interested--in my "Personal Experiences in Spiritualism," where copious extracts from the shorthand notes of the American sittings are given. To return, however: If there is a criticism to make of Mr. Bruce's book, it is that it displays a lack of personal investigation and experimentation, and bears throughout the ear-marks of a literary compilation. But this is, after all, not a serious detraction from a work of this character,--which is, as I have said before, excellently done. HEREWARD CARRINGTON.
