This volume is the French translation of the report of a commission of the Swedish government which investigated the subject of arsenicism exhaustively. In this edition the full case reports are omitted and only a few illustrative cases included. In its earlier stages this commission had the advantage of the services of Bang, and later of Ramberg and Wirgin, who elaborated microchemical methods by which infinitesimal amounts of arsenic could be accurately tested. Quantities as small as 0.0002 mg. in 10 cc. of blood can be recognized by this technic, which is based on the electrolytic reduction of arsenic at a mercury cathode.
In the first place, it was noted in an extensive analysis of foods that the fish from some regions of the Baltic as well as certain inland lakes contained appreciable amounts of arsenic, and that after ingestion of a single large meal of these fish the urine
