This is a beautiful example of Francis McNally's 1866 map of world, featuring the highlands and lowlands of the earth, important volcanoes and the world's isothermal lines. An inset near the bottom features a wind chart. The map is color coded and marks various mountain ranges, peaks, volcanoes, table lands, plains, deserts, and several other topographical details. Continents are named but boundaries of countries are not shown. This map was issued as map no. 1 in McNally's System of Geography.
