In the second series there were 123 trials; in 15 cases no impression was received, and in 35 cases, or 32 per cent of the remainder, an incorrect description was given. In the third series, of 133 trials there were 24 in which no impression was received and 40 failures: proportion of failures = 37 per cent. Mr. Guthrie attributes this gradual decline in the proportion of successes to the difficulty experienced by both agents and percipients in maintaining the original lively interest in the proceedings. No. 6.--By PROFESSOR LODGE, F.R.S. Subjoined is a detailed description of experiments made on two evenings in 1884, recorded by Professor Lodge,[22] which leaves no room for doubt that the impressions received in this instance by the percipient were of a visual nature. The agent on the first evening was Mr. James Birchall, who held the hand of the percipient, Miss R. The only other person present was Professor Lodge. The object was placed sometimes on a wooden screen between the percipient and the agent, at other times behind the percipient, whose eyes were bandaged. The bandage, it should be observed, was a sufficient precaution against cornea-reading; but for other purposes no reliance was placed upon it. It is believed that the precautions taken were in all cases adequate to conceal the object from the percipient if her eyes had been uncovered. In the account quoted any remarks made by the agent or Professor Lodge are entered between brackets. _Object_--_a blue square of silk_.--(Now, it's going to be a colour; ready.) "Is it green?" (No.) "It's something between green and blue.... Peacock." (What shape?) She drew a rhombus. [N.B.--It is not intended to imply that this was a success by any means, and it is to be understood that it was only to make a start on the first experiment that so much help was given as is involved in saying "it's a colour." When they are simply told "an object," or, what is much the same, when nothing is said at all, the field for guessing is practically infinite. When no remark at starting is recorded none was made, except such an one as "Now we are ready," by myself.] _Next object--a key on a black ground._--(It's an object.) In a few seconds she said, "It's bright.... It looks like a key." Told to draw it, she drew it just inverted.
