Note 151 — SECTION IV. POLITICAL GEOGRAPHY OF ICELAND.

Sir George S. Mackenzie makes the desert tracts of inner Iceland to number 40,000 square miles, a figure which still deforms Lyell’s admirable Principles of Geology, 11th edit., vol ii., p. 454. Mr Vice-Consul Crowe reduces the total area to 29,440 square miles (geog.), of which two-thirds are upwards of 1000 feet above sea-level, and only 4288 square geographical miles are covered with perpetual snow, whose line begins between 2000 and 3500 feet.
