Lettera dell' Abate Spallanzani al Sig. Marchese Lucchesini.

Records on pp. 80-104 Spallanzani's work on the torpedo. In the 1780's Spallanzani turned to marine biology, making several trips to the Mediterranean region. On his visit to Portovenere in 1783 "he instituted the first marine zoologial laboratory. . . . He refuted the claim that the torpedo fish was attracted by magnets, intrepidly showing that its greatest shock was delivered when the fish was laid on a glass plate. Excising the heart did not lessen the shock until the circulation began to fail "(DSB).
