Abstract

A sober account of some striking examples of various "para-normal phenomena," like telepathy, clairvoyance, materializations, and poltergeists. The author tries to show that "here in para-psychology are facts which completely undermine the complacent materialism of the past century." He adduces interesting evidence derived from experiments and controlled observation, but the explanatory hypotheses put forward are less convincing.--R. G. S.
