The third recurrence of the heat wave culminated on Wednesday
in a shade temperature which has never been exceeded in the 54 summers during which records have been kept. At 2.15 p.m. 971 degrees were registered in Camden Square, while a temperature of 100 was reported from Greenwich Observatory which is said to be the highest shade temperature ever registered in Great Britain. Work on some foundries and farms had to be discontinued, and infantile mortality shows a considerable increase. Dr. Mill, who contributes an interest- ing letter to Thursday's Times, notes how little effect on the routine of daily work in London is produced by a temperature which would be considered high in Calcutta, and which has, he believes, never been reached in Colombo.
