• In the open, there are no reflecting walls or surfaces, and the original sound has no re?nforcement from reflection. Bertha M. Clark. General Science.
• The ends of the rails were not japanned, but were electroplated, to give good contact surfaces for fish-plates and copper bonds. Frank Lewis Dyer. Edison, His Life and Inventions.
• When light from any luminous object falls upon books, desks, or dishes, it meets rough surfaces, and hence undergoes diffuse reflection, and is scattered irregularly in all directions. Bertha M. Clark. General Science.
• Heated casts of previously carved models were pressed into or on to wet wood, and the charcoal surfaces then brushed off with hard brushes. William Henry Doolittle. Inventions in the Century.
• Also The combination of a needle and a shuttle, or equivalent, and holding surfaces, constructed and operating substantially as described. William Henry Doolittle. Inventions in the Century.

• Also The combination of holding surfaces with a baster plate or equivalent, constructed and operating substantially as described. William Henry Doolittle. Inventions in the Century.
• The Wrights realized that a more automatic method of meeting these changes must be found, and they worked it out by shifting the rudder and the surfaces of the airship as it met the air-currents. Rupert S. Holland. Historic Inventions.
