| To EY+ from EFC. c. BY/RD. X 4646 EFC2/T2.11.25. X.4646 - BONE GREY FIBRE. The bone grey fibre actually being used on production appears to be darker in colour than the sample upon which most of the experiments were made, a portion of which will be found attached. It may be just the same in effect, but to make sure of this perhaps it would be as well to give Mr. Brock this sample and for him to say whether it shapes up in a similar way. At the same time, a second portion is(attached) of the sample received from Spauldings, with which we have dealt in our note EFC1/T2.11.25, could also be handed to the shop for another comparison.
