    Notes: [Auszug] We have measured the time of burning of droplets suspended at the end of a silica filament or metallic wire by a photographic method in still air. The time of burning, T, is found to be directly proportional to the square of the initial diameter of the droplet, d0, over the range of drop-size ...
