§ MR. NANNETTI (Dublin, College Green)I beg to ask the President of the Board of Trade whether the oil lamps to be used in the new Fastnet lighthouse are to be the ordinary Trinity House mineral oil lamps or any improved method of burning petroleum; whether there are to be two lamps superposed, both lighted in all weathers; how many lenses will surround these lamps: what angle will each subtend; and what will be the duration of the flash which is to appear every five seconds.
§ MR. GERALD BALFOURI am in formed by the Trinity House that the lamps to be used in the new Fastnet lighthouse are incandescent oil burners, and not oil burners of the ordinary Trinity House type. There will be two lamps superposed, which will be lighted in all weathers, with four lenses round each burner. The angles will be eighty vertical and ninety horizontal, and the duration of the flash will be 16 second.
