242 Mi: J. Drummond's Table of Earthquakes at Comrie. 



To come to the register, I must observe that it gives the state 

 of the river, then the number of what I call gas explosions, 

 next the hour at which the vertical shocks occurred, the num- 

 ber of them, and the utmost distance at which felt ; afterwards 

 the lateral shocks, and then the tremours or waving shocks, 

 and lastly the state of the weather. The noises, which I am 

 inclined to consider as arising from gas explosions, are only 

 heard at Comrie, Tamperran and Leachkin, the site of the 

 vertical shocks.
