| X6110. EFC. BY/RD3/W.1-11-30. We attach herewith a sample of Wax used for impregnating electrical apparatus, which has a melting point of 84°C., as compared with our standard Paraffin Wax which melts at 47°C. This new Wax is known as Hallowax, and we should be glad if you would test the sample for its insulating properties as compared with our standard Wax used on Production, a sample of which can be obtained from Mr.Brock.
