| Title | Copy letter from Robert William Frederick Harrison, to The Manager, St James's & Pall Mall Electric Light Company |
| Date | 5 January 1911 |
| Description | Harrison would like to understand more clearly the method of charging by two meters whose readings are added together to make up the current charged. Asks if he is right in supposing that the current is brought into the building on two main leads instead of one and that each has its own meter. |
