great depth and at a high angle as Perrey of Dijon gti to suppose the

observed that at the rate of propagation given by Mallet for earthquake 
waves through hard rock, which is not less than 10 ,000 feet per second, 
it is quite possible that even a ean wave may appear to be felt at 
the same instant at great dist

also very generally noted that it was most severely felt on low ground 
and least so on rocky eminences. This last character which belongs to
