|Copy letter from Robert William Frederick Harrison, to Fred Enock, 42 Salisbury Road, Bexley, Kent
|6 June 1906
|Harrison explains that Enock can reserve the electric lantern in the meeting room for use on the 20 June, but they cannot arrange an extra one due to the space requirements of an exhibit already arranged, which involved the setting up of a lantern and apparatus additional to the Royal Society's own. An operator will be available to show Enock's slides.
