3219. Map of the Earth, projected on a regular Icosa- 

 hedron. George H. Darwin. 



In these maps, the representation of the earth is effected by supposing the 

 globe to be inscribed to a regular dodecahedon or icosahedron, and then 

 projected on the faces of the solid by lines radiating from its centre. The 

 faces of the solid are then opened out and laid flat, in such a manner as to 

 represent the equator by a straight line. In the case of the icosahedron the 

 polar axis is supposed to pass through two corners of the solid. In the case 

 of the dodecahedron, the polar axis is supposed to pass through the middle 

 points of two opposite facee, and these two faces are cut up into triangles.
