From page 19... ...
Whittaker (1960) explains the mist reports as uncritical interpretations of the occasional absence of familiar fine detail because of poor seeing conditions.

From page 20... ...
He concluded that the molecules were outgassed from the lunar interior in a volcanic eruption, and exhibited emission bands due to the cascade of absorbed solar ultraviolet photons to lower molecular energy levels (fluorescence)

From page 21... ...
Kozyrev's spectrum shows emission from the central peak only, and Opik finds it difficult to understand how the observations can be explained as gas emission. However, if the gas were emitted from a fissure or volcanic cone at a temperature~104 °K, lunar escape velocity would be achieved, and the expanding cloud would have a conical envelope of small half-angle.
