Sidis, Boris, and Goodhart, Simon Phillip. Multiple personality: an experimental investigation into the nature of human individuality. [**]$2.50. Appleton.

In the main this work is the analysis of a reactionary second personality resulting from an accident befalling the Rev. T. C. Hanna a few years since. When he returned to consciousness, he was possessed of an entirely different self, “which may be understood only by comparing it to the birth of a person possessed immediately of matured mental and physical functions.” The phenomena of this state, the return to his primary personality, and the struggle which the physicians experienced in establishing him once more on the mental basis of his former self—there being for some time a Dr. Jekyll and Mr. Hyde tendency to alternate between the two human individualities—make a study as strange as it is interesting and important to the scientific world.

“The close and accurate study of Mr. Hanna’s case throws a flood of light on personality and cognate themes, and is a most valuable contribution to the literature of psychopathy.” Albert Warren Ferris.

“The most original as well as most interesting portion of the volume is given over to a painstaking account of a remarkable loss of personality, in many respects the most complete on record.”

“Dr. Sidis finds corroboratory evidence in support of his view that multiple consciousness is the law, not the exception.”

“Truly one of the most fascinating of the fairy-tales of science, for the observing and recording of which Dr. Sidis and Dr. Goodhart deserve all credit.”
