§ Mr. Bevins
Investigations by the Admiralty into the causes of corrosion began sometime in the 17th century. They have continued ever since. Organised research by otherGovernment Departments is of comparatively recent origin. The Ministry of Supply is carrying on work started at Woolwich during the First World War: organised research sponsored by the Department of Scientific and Industrial Research started in 1921; andthe Post Office have been engaged on it for at least twenty-five years. Much progress has been made towards a full understanding of the causes of corrosion and in devising methods of prevention. These methods are being applied both by Government Departments and by industry.
