BAEOMETEICAL FLUCTUATIONS AND EAKTHQUAKES. 269 



examples when there has been a fall of temperature at 

 the time of an earthquake.^ 



At Kiachta, in Siberia, at the time of the earthquake 

 of December 27, 1856, the thermometer fell from 12° to 

 25>° E. We must, however, remember that there are 

 many cases known where the thermometer rose. 



M. S. di Kossi remarks that we have the highest 

 records of temperature in the years richest in earthquakes. 

 Thus, in 1873, at the time of the earthquakes in Central 

 and Northern Italy, an abnormal high temperature was 

 remarked. Japanese writers have remarked upon the 

 unusual heat which has shaken their countries. The 

 temperature of subterranean waters have been known to 

 increase before earthquakes.
