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. | | | | [95] _Phil.
