[95] A notable example of a rapid diminution in the number of earthquakes felt at a place is that of Comrie in Scotland. In 1839–40, no less than sixty shocks were felt in eleven months. In 1842–43, about thirty shocks were felt, and in the following year thirty-seven. Since this time the number of shocks has decreased until they are almost of as rare occurrence at Comrie as in other portions of the British Isles.
