‘Third Report of the Committee on Thought-Transference’, Proceedings of the Society for Psychical Research, 1 (1882–3), pp. 161–216.

At the close of the last Report a series of experiments were recorded illustrating the reproduction of drawings without any discernible communication passing between the Agent, Mr. Blackburn, who had momentarily seen the drawing made by one of us, and the Percipient, Mr. G. A. Smith, who was blindfolded throughout the experiment. The experiments began on January 19th, 1883, and were continued for three or four days in succession. During this series of experiments a considerable number of drawings were made, nearly all of which were exhibited at the following General Meeting. In some of the less accurate reproductions Mr. Blackburn complained of the difficulty he had in keeping the original drawing steadily in his mental view.
