Frear Weather a hair hygrometer
 
The "Frear Weather" is a hair hygrometer

The humidity is one of the important measurements that weather observers make because the amount of water vapor in the air determines whether clouds or fog are likely and whether it's going to rain or snow.

Human (or animal) hair turns out to be a pretty good way to measure the humidity.

The "Frear Weather" is a hair hygrometer. The hair hygrometer was so reliable that it was not replaced by an electrical instrument until the 1960s.
