Excerpt from Extracts From the Report of Her Britannic Majesty's Commissioners, Appointed to Inquire Into the Condition and Management of Lights, Buoys, and Beacons: Submitted March 5, 1861, and Presented to Both Houses of Parliament by Command of Her Majesty; Republished for the Use of the U. S. Light-House Establishment This fault was not found to exist in the lights under the Northern Commissioners, who make use of a mechanical pump lamp, which burns on an average seven hundred and ninety-four gallons of oil annually, and produces good flames of about double the height of those in England or Ireland. Other remarks on the want of reflectors on the land side of the appa ratus, on the injurious effect of the shoulder of the lamp-glass. On the erroneous position of astragals, on the want of filters, medicine chests, clocks, signals for day, night, during fogs, &c., will be frequently found among the personal observations of your Commissioners, and in the special report on the Whitby lights.
