In June 1875, Paul Boyton, “the fearless frogman,” crossed the English Channel enclosed in “Merriman’s Life Preserving Dress,” an inflatable rubber suit designed to float 300 pounds. “Over 1500 persons had assembled on the piers,” reported the Science Record, “and the house-tops in the vicinity were covered with spectators.”

The remarkable suit carried provisions for nine days, and “it is impossible for the body to sink, or, however tossed by a rough sea, to be thrown face downward.” Far from it: Boyton showed crowds how a floating man could display a flag, dispatch a carrier pigeon, build a raft, smoke, read, fish, cook, and shoot.

Ironically, he dazzled his way right out of the record books. Because the miraculous equipage included a sail and a paddle, Boyton’s feat scarcely counts as swimming, and credit for the first channel crossing today generally goes to Matthew Webb, who swam from Dover to Calais two months later the old-fashioned way.

A man about 43 years of age giving the name Joshua Coppersmith has been arrested for attempting to extort funds from ignorant and superstitious people by exhibiting a device which he says will convey the human voice any distance over metallic wires. He calls the instrument a ‘telephone,’ which is obviously intended to imitate the word ‘telegraph’ and win the confidence of those who know the success of the latter instrument. Well informed people know that it is impossible to transmit the human voice over wires, as may be done by dots and dashes and signals of the Morse Code. The authorities who apprehended this criminal are to be congratulated and it is hoped that punishment will be prompt and fitting, and that it may serve as an example to other conscienceless schemers who enrich themselves at the expense of their fellow creatures.
