The following table gives the average for each month of 1962 of the daily
readings of the concentrations of smoke and sulphur dioxide at a further two
recording stations. The highest and lowest readings for each month are also shown.
Both smoke and sulphur dioxide concentrations are calculated in microgrammes per cubic metre:-
