As will be seen from the second map the catastrophe of 800,000 years ago caused very great changes in the land distribution of the globe. The great continent is now shorn of its northern regions, and its remaining portion has been still further rent. The now growing American continent is separated by a chasm from its parent continent of Atlantis, and this no longer comprises any of the lands now existing, but occupies the bulk of the Atlantic basin from about 50' north to a few degrees south of the equator. The subsidences and upheavals in other parts of the world have also been considerable--the British Islands for example, now being part of a huge island which also embraces the Scandinavian peninsula, the North of France, and all the intervening and some of the surrounding seas. The dimensions of the remains of Lemuria it will be observed, have been further curtailed, while Europe, Africa and America have received accretions of territory.
