Mean temperature of the day in the summer of 1852: 83.23

Mean temperature of the night: 71.38

It is, moreover, shown that the most disease does not prevail at the periods of the most excessive heat but during the intensest nocturnal transitions of temperature.

1. Rain fell through the greater part of May, and the S.W. wind prevailed during the latter half. In June there was much rain, and four days of thunder and lightning, when the wind was in the E. In the latter part of this month there was much rain, and the wind was in the S.W. There was rain also in July and August, and it continued until the end of September, when it became fine and continued so, with occasional showers, through October and November; during the last two months the N.E. winds prevailed, with occasional breaks of S.W., E. and N. winds.

It is very undoubtedly only reasonable to ascribe much of the improvement in the health of the troops during the last two years to circumstances in which human...
