“It is a violet.”

The Professor and Mlle. C have nearly finished their entertainment. But before bowing farewell to the company, he approaches a little girl, let us say in the audience, and in a whisper asks her age. With the utmost secrecy she informs him that she is just nine.

“Pray, how old is my little friend here?” he demands of Mlle.

“Nine years old,” she replies at once.

“What is your name?” whispers the Professor to the little girl.

“Margery,” she whispers back.

“Now! Be sure! Having found so easily, if you please, her age, what is the young lady’s name?” (N = m, b = a, s = r, h = g, f = e, s = r, easily = y.)

“Her name is Margery,” is the reply; and with this pretty example of his power, the Professor will close the evening.

I have dealt at such length with the Professor and his codes, because it is the easiest and most general system of mechanical second-sight. But Professor B and Mlle. C have yet another system of second-sight, more puzzling still to the spectators, as not a word is exchanged between either of the confederates during the whole performance.

Seating the lady upon the stage, facing the audience, and omitting to bandage her eyes, Professor B goes down amongst the spectators as before, examines various articles, is told different numbers and touches sundry objects exactly as in the former entertainment. Without speaking a single word he merely glances at Mlle. C, who after a few seconds mentions the number or describes the article as the case may be.
