Extract

In summarising, the following points are to be noted:—

1. The thermal death point of the blow-fly was definitely influenced by the factor of humidity.

2. Saturated and dry air had the effect of lowering the thermal death point.

3. Relative humidities from 60 per cent. to 80 per cent. were more favourable, while relative humidity of 70 per cent. actually was found to be an optimum point.

4. From the weighings it may be concluded that death in saturated air was due to the inability of the flies to regulate their heat by evaporation.
