The depths of the sea are marked by contour lines without 

 any difference of colour the contour lines corresponding to 

 100 metres, 500 metres, 1,000 metres, and 2,000 metres. The 

 general colour of the sea is blue. The lakes are shown in a 

 deeper shade of blue, and the " chotts " of Africa by a lighter 

 shade. The land is coloured brown. The higher elevations are 

 coloured in a deep tint, so as to make the relief more visible. 

 Perpetual snow is marked in white, and volcanoes by a red spot. 

 The political boundaries by red lines.

The depths of the sea are show n by contour lines, and also by 

 shades of colour, the greatest depths by the lightest shades. 

 The contour lines correspond to 100, 500, 1,000, and 2,000 

 metres. The rocks are indicated by 11 colours, representing 

 Quaternary deposits, Tertiary, Cretaceous, and Jurassic rocks, 

 Trias and Permian together, transition rocks, i.e., Carboniferous 

 to Cambrian, Primary, meaning gneiss, granite, &c., porphyries, 

 volcanic rocks distinct from the last, and unknown rocks. The 

 geology, therefore, is not of the modern kind, and there are no 

 names of countries, rivers, seas, or other features.
