The standing difficulty with the normal bulbed pipette is to clean the inside surfaces of the bulb. With a new pattern introduced by the writer the whole of the inside surface can be reached for cleaning. Pipettes have been made to this design by Messrs Baird and Tatlock, Ltd. (London).

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 (Fe2O3) 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.
