THIS volume reminds me of the mountain which gave birth to a mouse. Its length would be excusable if only it marked a step in advance in the field of psychology or physiology, or as to the question of the supernormal. As such is not the case, it is unpardonable, and nothing more is left me to do except to make clear its deficiencies in this triple aspect.

Smith, as is doubtless true of all mediums, presents during her visions and somnambulisms a plenitude of disturbances of motility and sensibility, from which she seems entirely free in her normal state. But these trifling observations do not suffice to solve the neuropathological problem of mediumship, and the question still remains open as to whether that term corresponds to a special category of manifestations and to a distinct syndrome, or whether it merely constitutes a happy euphemism for various scientific denominations already in use. To endeavor to fix the connections of mediumship with other functional affections of the nervous system, THE END CONCLUSION
