The scale of height throughout the whole section is also infinitely greater than that of breadth. The plants and animals also are figured on no uniform scale. Is an imaginary Section constructed to express, by the insertion of names, and colours, the relative positions of the most important classes, both of unstratified and stratified rocks, as far as they have yet been ascertained. The crowded condition in which all the Phenomena, are set together, does not admit of the use of accurate relative proportions, between the stratified rocks and the intruded masses, veins, and dykes by which they are intersected. The extent of the different formations, taking their average width as they occur in Europe, would occupy a breadth of five or six hundred miles. The bones of the Dodo have been found under lava of unknown age in the Isle of France, and in a cavern in the Island of Roderigue.
