Insufficient No. of results.
* These high figures indicate the considerable increase
in smoke particles and sulphur dioxide during thick fog.
Measurements were not being taken in this district during the
comparable fog period of 1952 so direct comparisons cannot be
made but the general indication is that the increase and
consequent casualty rate were much less on this occasion,
reflecting the benefit of smoke control.
