| Title | Letter from F W Bowden, City & Guilds of London Institute, Technical College, Finsbury, Leonard Street, City Road, London, to [John] Percy |
| Creator | Bowden; F W (fl.1890s); British |
| Recipient | Percy; John (1817-1889); British metallurgist |
| Date | 26 February 1895 |
| Description | He gives the results for two experiments suggested by Percy: a Leiden jar experiment, in which the electrometer was too sensitive to read the necessary voltage, a difficulty which was overcome; and a second with a magnetic field. He sketches the latter, involving the rise and fall mercury in a standpipe with an electromagnet providing current and reversed current within the tube. |
