Extracted from The Philosophical Transactions of the Royal Society for the year 1896. In this important experiment aimed at understanding the ability of electric fish to stun smaller fishes and even numb a human hand while not causing harm to themselves or others of their species, Gotch and Burch recorded electrical activity using a capillary electrometer, finding “that the discharge of a single ‘disk’ of the fish’s organ was in the range of 40 to 50 mV, and thus similar to that of nerves” (Finger, The Shocking History of Electric Fishes, 408). Handsomely illustrated. Item #1057
