Mr D. Milne on Earthquake Shocks in Great Britain, 107 
pursuits, added the advantages of a good education, and of con- 
siderable natural talents; and being obliged, from his office, 
to be almost constantly at home, there was no risk that shocks 
would occur which Mr Macfarlane would not perceive and 
register. He had begun, even before the author’s acquaint- 
ance with him, to jot down the shocks as they occurred, as 
well as to turn his attention towards the invention of instru- 
ments for marking them, and in which he displayed much me- 
chanical skill. Having prevailed upon Mr Macfarlane to keep 
aregular register, the author is now enabled to give a table of 
all the shocks which have occurred at Comrie during the last 
two years.
