The first geological map of Scotland has a history not less interesting than that of Smith's famous map of England; seeing that what Smith accomplished, single-handed, for the southern part of Britain, John Macculloch did, with the same independence of all extraneous aid, for the northern half of the Island. Smith's fame has happily been long since vindicated; but, owing to a variety of circumstances, Macculloch has never received full credit for his grand work; on the contrary, his fair name and even his veracity have been too often cruelly aspersed.
