| c. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} BEARING METAL. I am sending you herewith a sample bearing, which has been supplied by D.{John DeLooze - Company Secretary} MacIntyre of Sandgate House, Lichfield Road, Four Oaks, also a copy of his letter describing the bearing. I think it would be interesting to try out a bearing in comparison with your own material, with the object of ascertaining what its commercyial value is likely to be. The bearing metal is an alloy of aluminium, copper and lead, graphited. I am interested in knowing whether it is possible to detect the presence of the graphite on a micrograph in the composition of the alloy. I think we should investigate this bearing metal to see whether it has any real claim for superiority, and to this end I would suggest, if Hs.{Lord Ernest Hives - Chair} and Rm.{William Robotham - Chief Engineer} agree, that they might make up a set of Bentley bearings.
