This is a historical piece I wrote for the March issue of Natural History magazine:
In November, 1774, a cask of rum arrived in London, spiked with four dead electric eels, the largest of them three feet eight inches long and up to 14 inches around. They had smooth, snaky bodies, flattened heads, blunt snouts with a pronounced underbite, and two small fins, resembling ears, at the sides. Their eyes were small and round, and their dark facial skin was heavily pockmarked, as if with the point of a knitting needle.
The eels, actually knifefish of the species Electrophorus electricus, had come from the Suriname River in South America, and the sensation they caused in England was literally electrical. One of them had survived aboard ship all the way to the port of Falmouth, in southwestern England, and duly delivered electric shocks to British thrill-seekers, before finally expiring. But even dead and consigned to rum, a standard preservative then, the specimens still had the power to excite educated minds.
John Hunter, master dissector, avid client of grave robbers, Surgeon-Extraordinary to King George III, and father of modern surgery, “danced a jig when he saw them, they are so compleat and well preserved,” wrote his equally eminent naturalist friend Daniel Solander.
