and especially in Scotland, 363 



shocks from the 19th December 1838 to the 8th March 1840. 

 The shocks so registered, were felt at St Jean de Maurienne, 

 in Savoy, a place where the sun comes to the meridian about 40 

 earlier than at Comrie. As the time of each shock is given 

 in hours and minutes in this register, means are at once af- 

 forded, for judging whether the shocks at St Jean de Maurienne 

 and at Comrie corresponded in point of time. 



The following are the results of this comparison : — (1.) The 

 two Registers run together for five months, viz. from October 

 1839 to March 1840. (2.) During that period, 130 shocks 

 were felt at Comrie, and 58 at St Jean de Maurienne. (3.) 

 At Comrie, the most violent and the greatest number of shocks 

 occurred in October 1839, whilst at St Jean de Maurienne, 

 December 1839 was the month, during the above period, in 

 which they were mast frequent and severe, (4.) Whilst at 

 Comrie there were, during the above period, about 61 days 

 on which shocks occurred, at St Jean de Maurienne ther6 

 were only 22 days. (5.) During the above five months, when 

 shocks were occurring so frequently at both places, there 

 were only eleven days on which shocks were felt at both, 

 within the same space of twenty-four hours. (6.) So far from 

 any of the shocks, on these days, having happened at St Jean 

 de Maurienne about 40' before they were felt at Comrie, no 

 shocks occurred at the two places nearer one another than 

 3^ hours ; and no regularity of intervals between the shocks- 

 of the two places, is discoverable. 



These results shew conclusively, that the shocks of earth- 

 quake at St Jean de Maurienne, have no correspondence or 

 connection, in regard to the period of their occurrence, with 

 those at Comrie. Indeed, the circumstance stated in the report 

 on these earthquakes, that the shocks caused by them were 

 not in general felt to extend into Piedmont, prove that, just 

 as at Comrie, the origin of them cannot be very deeply seated. 



But v/hat is thus proved of earthquakes in Savoy, viz. that 

 they have no connection with those occurring in Great Britain, 

 will be found to hold equally good of earthquakes occurring 

 in other parts of the world. Some trouble has been taken 

 to collect notices of sue, and a number have been collected
