| Title | Paper, 'An apparatus for testing the sensitiveness of safety-lamps' by Frank Clowes |
| Creator | Clowes; Frank (d 1923); British chemist |
| Date | 1891 |
| Description | Clowes writes: 'It is generally acknowledged that the Davy safety-lamp cannot with certainty detect less than 3 per cent, of firedamp in the air of the mine. Gas-indicators of much greater sensitiveness have been invented; amongt these the electrical apparatus of Liveing and the spirit safety-lamp of Pieler take first rank. The objection to these special forms is, however, a serious one.'
