The first of these decapitated criminals being conveyed to the apartment provided for my experiments, in the neighborhood of the place of execution, the head was first subjected to the Galvanic action. For this purpose I had constructed a pile consisting of 100 pieces of silver and zinc. Having moistened the inside of the ears with salt water, I formed an arc with 2 metallic wires, which, proceeding from the 2 ears, were applied, one to the summit and the other to the bottom of the pile. When this communication was established, I observed strong contractions in the muscles of the face, which were contorted in so irregular a manner that they exhibited the appearance of the most horrid grimaces. The action of the eye-lids was exceedingly striking, though less sensible in the human head than in that of an ox.
