On the basis of the CLE. (1931) colour metric an expression is developed for the colour co‐ordinates and luminosity of a given light source seen at night through an atmosphere of known optical properties. This is applied to an observation on a mercury vapour lamp in a highly selective haze of the type sometimes called “blue fog”.

A detailed analysis of the rainfall of Adelaide, South Australia, has shown that throughout the 95 years 1839‐1933 there has been a definite oscillation, with a period and amplitude of approximately 23 years and 30 days respectively in the incidence and duration of the winter rains. The amplitude, though small, is nevertheless about 20 per cent of the length of the rainfall season. The total quantity precipitated has shown no statistically significant changes.

The cold Benguela current flowing northward along the West Coast of South Africa tends to keep the temperatures along the seaboard low and uniform. On the other hand, under eertain pressure distributions hot dry fdhnlike winds, coming down from the interior 3,000ft.‐plateau, and known as berg winds, cause remarkably high temperatures along the coast on the days when they occur. These berg winds are mostly in evidence during the months April to August, their frequency during this period being about eight days per month.

The lunar atmospheric tide a t Melbourne, Australia, has been determined from nearly 36 years' record; the mean result is 28 sin (2t +84.0°) microbars, with a probable error of 2.3 microbars. This is compared with the determination made by Neumayer from data for the years 1858‐63: his result is found to be affected by so large a probable error as to be practically without value.
