Temperature was greatly against a reduction in power. The Relative Humidity effect would probably about average, though the Humidity in No. 2 Room shows a considerable increase for the first test over the outside condition, due to artificial means. This would act towards increasing the power for that one room as compared to a lower per cent. of Relative Humidity.

The temperature was 15 degrees Fahr. lower during the second test which would be much against the reduction in power.

The Relative Humidity, however, was also lower which would be in favor of the reduction in power. These two influences would in all likelihood balance each other so that it may be considered that the atmospheric conditions were the same.

The difference (17.9 H.P.) is to be deducted from the 2nd test.
