Copy letter from Robert William Frederick Harrison, to George Matthey, Fellow of the Royal Society Harrison communicates that the Soiree Exhibits Committee will be happy to receive specimens of fused silica, as well as articles in the metals rhodium, iridium and ruthenium for exhibition on 8 May. He wishes to check that Matthey does not object to the Committee's proposal to invite Thermal Syndicate Limited to show examples of their fused silica ware. He encloses a schedule for particulars of Matthey's exhibit, and states that if he is able to give an indication of the space required, they can give a better idea of how far they can accomodate his requirements. 12 April 1907
