| Description | Referring to his letter of 7 May regarding the Soiree, the voltage here [at the Royal Society, Burlington House] is 105, direct current. As he asked for an eight foot long table for the illumination of lantern slides, it was assumed that they would be shown in the usual way in a frame, and could therefore be placed on a table and lighted from behind with the linolite light. Since it seemed rather a long frontage, the point was brought to his notice, as space is precious. All electrical requirements are communicated to the electrician in charge, who has the personal supervision of wiring, insertion of fuses. |
