STORE FRONTS.      A modern store front should be equipped with Luxfer Prisms in the form of transom panels above show windows and entrance doors. These panels are composed of prisms four inches square, glazed together by our electro-glazing method in solid copper, producing an absolutely air and water tight panel stronger than plate glass to resist wind pressure, without the use of steel strengthening bars. Our standard copper finished glazing is also a strong and satisfactory method. The prism panels should extend across the full width of storerooms, as shown in cuts herewith (Figs. 4 and 5). Roller awnings set on transom bar should be used where awnings are necessary, and clear glass should be installed in the upper part of rear partition of show windows if they extend beyond the transom bar of front window. Splendid results and great economy in the cost of artificial lighting can be effected by also equipping the windows in the rear of storerooms.     Light wells and ceiling lights occupying valuable floor place, and a source of great danger in case of fire, can be entirely dispensed with when a building is equipped with the Luxfer System.

FOR OFFICE AND APARTMENT BUILDINGS.     Dark offices and apartments can be made light and cheerful and their earning capacity increased by the Luxfer System. LUXFER PRISM CANOPIES.     The Luxfer Prism Canopies (Figs. 6 and 7) constitute an invaluable adjunct to any present day office buildings, stores, apartment buildings and residences. Their value is readily apparent in a narrow street or court where high buildings opposite deny the admission of direct light. In order to relieve this condition and receive the requisite amount of light upon the prism panels, the latter are set at an angle to the vertical wall, or in a position similar to that of an awning.
