Q. What sort of weather may we expect if the barometer be very fluctuating?
A. If the mercury fluctuates much, the weather will be very changeable and unsettled.
The fall of the barometer.
In very hot weather, the fall of the mercury denotes thunder.
Except in very hot weather, the sudden falling of the barometer denotes high wind.
In frosty weather, the fall of the barometer denotes thaw.
If wet weather happens soon after the fall of the barometer, expect but little of it.
In wet weather if the barometer falls, expect much wet.
In fair weather, if the barometer falls much and remains low, expect much wet in a few days, and probably wind.
