| Title | Copy letter from Robert William Frederick Harrison, to T E Heath, 53 Park Place, Cardiff |
| Date | 26 April 1906 |
| Description | Harrison communicates that the Royal Society feels it cannot introduce an arc light or limelight for Heath's exhibit, and suggest that he adopt the simple method initially proposed. The Society's continuous current voltage is 105, so there should be no difficulties regarding his lamps. Anything needed to make his exhibit a success will be carried out. |
