An Influencing Machine

Wrocław, Poland

"As boys raise a kite in the air, so these wretches, by means of the air-loom and magnetic impregnations, contrive to lift into the brain some particular idea ... and how much soever the person assailed may wish to direct his mind to other objects, and banish the idea forced upon him, he finds himself unable." John Haslan, Illustrations of Madness, 1810
