That is, about 40 living forms secrete a substance called luciferin. In the presence of moisture luciferin oxidizes, forming oxy-luciferin, the substance which actually glows. As oxy-luciferin glows it loses its oxygen and returns to luciferin, which after a short rest may be oxidized again...
...Torpedoman Edward Kalinowski climbed through the escape hatch. He released a cork buoy attached to a life line, the other end of which was fastened to the submarine. Then grasping the life line he ascended. He was followed by Lieut. Charles B. Momsen, co-inventor of the mechanical "lung" (oxygen mask) with which both were equipped. The two men ascended 20 ft. at a time and then rested, holding the life line to keep themselves from bobbing quickly to the surface and meeting death from the sudden change of pressure. From 160 ft. they rose in 13 minutes, from...

Then, if one could arrange a little flag so that it would run around the track at a steady speed just a little higher than the average speed of the previous record holder, and instruct the runner to follow the flag exactly, one would eliminate another...
