V. On some phenomena connected with cloudy condensation

Abstract

In the first part of this communication I intend giving the results of an investigation into the phenomena connected with the cloudy condensation produced when a jet of steam mixes with ordinary air, with special reference to the marked change which takes place in the appearance of the jet by electrification and other causes. In the second part will be given the results of an investigation into certain colour phenomena which can be produced when the condensation is made to take place under certain conditions, and it is thought that these experimental colour phenomena, if they do not give the explanation of a “green sun,” at least enable us to reproduce it artificially with the materials existing in our atmosphere.
