"The glass roof is commonly designed so as to form a uniform plane or slope from back to front in lean-to houses, and form center to sides in span-roofed houses. In some cases, however, the roof sashes are fitted up on the ridge-and-furrow principle invented by Sir Joseph Paxton." — Encyclopedia Britannica, 1893

"A very powerful and economical one, for large establishments especially. It is a modification of the well-known Cornish boiler, and consists of two wrought-iron cylinders substantially rivetted together, and having a water space of about 2 inches between them. The frame for the furnace doors d is attached to the front. It is supported by two cast-iron chairs a, a, the front chair forming the frame for the lower flue doors b, which fasten by a simple catch, and can readily be lifted off for cleaning the flues. The plug c, opened by unscrewing it, is for the purpose of clearing out all interior accumulation of dirt, which should be done thoroughly at short intervals. The flow pipe is at e, the return at f." — Encyclopedia Britannica, 1893

"M. Cailleter's apparatus is represented. The gas under experiment is contained in a stout glass tube of narrow bore. To fill this tube with gas, both ends being open, a globule of mercury is first introduced at the lower curved extremity; the tube is then placed in a nearly horizontal position, the curved extremity is connected with the holder contraining the gas, or with the apparatus in which the gas is being evolved, by means of caoutehone tubing, and a current of the pure dry gas is passed through the tube until the air is entirely expelled; this being effected, the point opposite to the curved extremity is sealed in the blowpipe flame; the tube is then brought into a vertical position, so that the globule of mercury closes the lower extremity, the caoutchouc tube is withdrawn, and the tube AA thus filled is screwed into its place in the cylinder B." — Encyclopedia Britannica, 1893
