XXVII.—On the Parallel Roads of Lochaber

Abstract

I. The Parallel Roads of Lochaber have presented to geologists a problem, which is still unsolved. Dr Macculloch, about sixty years ago, when President of the Geological Society of London, first called attention to these peculiar markings on the Lochaber Hills, by an elaborate Memoir afterwards published in that Society's Transactions. He was followed by Sir Thomas Dick Lauder, who in the year 1824, read a paper in our own Society, illustrated by excellent sketches. His paper is in our Transactions. The next author who attempted a solution was the present Mr Charles Darwin. He maintained that these Roads were sea-beaches, formed, when this part of Europe was rising from beneath the Ocean. He was followed by Professor Agassiz, Dr Buckland, Charles Babbage, Sir John Lubbock, Robert Chambers, Professor Rogers, Sir George M'Kenzie, Mr Jamieson of Ellon, Professor Nicol, Mr Bryce of Glasgow, Mr Watson, and Mr Jolly of Inverness. Sir Charles Lyell, though he wrote no special memoir, treated the subject pretty fully in his works, giving an opinion in support of the views of Agassiz.
