The Effects produced by the Inhalation of Haematite and Iron Dusts in Guinea-Pigs

Abstract

THE production of a fibrosis due to inhalation of haematite in man has already been disucssed by Goadby (1925). The following experiments were made to see what effects were produced by exposing guinea-pigs to the dusts of ( a ) haematite (Fe 2 O 3 ) and ( b ) levigated iron. Finacial assistance towards these experiments was very kindly rendered by the Mines Department, to the Inspectors of which I am also indebted for the haematite powder from Cumberland.
