A Thermometer Falls: 



For change of wind towards any of the above direc- 

 tions. 



The Barometer Falls: 



For southerly wind (including from S. E. by the 

 south to the westward) for wet weather, for stronger 

 wind, or for more than one of these changes — except 

 on a few occasions when moderate wind with rain (or 

 snow) comes from the northward. 



A Thermometer Rises: 



For change of wind towards the upper directions 

 only. Moisture or dampness in the air (shown by a 

 hygrometer) increases before or with rain, fog or dew.
