In 1887, John Bartholomew's Gazetteer of the British Isles described Highland like this:
Highlands, generally speaking, that portion of the mainland of Scotland on and beyond the Grampians, in which the population is (or was) mainly Celtic, and the language Gaelic. The imaginary line between the Highlands and the Lowlands has commonly been regarded as commencing at the mouth of the river Nairn (at Nairn, on the Moray Firth); it runs thence SE. ...
to the Dee (at Dinnet, 4 miles W. of Aboyne, Aberdeenshire); thence S. to the West Water (a headstream of the North Esk, Forfarshire); and thence SW. to the Clyde at Ardmore (opposite Greenock). Some parts of this district, however (notably Caithness), are not marked by the usual physical features of the Highlands.
