, in a communication to the Chemical Society, gives a decidedly negative answer to the question whether the acids of canned fruits may not form poisonous salts with the tin. He reports, as the result of his experiments, that "tin is entirely devoid of danger when taken internally in any form that might arise from being in contact with fruits or vegetables." He believes that the cases of accidental poisoning attributed to tin were due to solder or other impurities—arsenic, copper, or lead. Professor W. Mattieu Williams says that there need be no lead in the solder—that it is only put in for cheapness' sake, and that tin makes a superior solder to any alloy. Therefore, all danger may be obviated by prohibiting the use of any other solder than pure tin.
