A period--speaking roughly--of between four and five million years probably represents the life of the continent of Atlantis, for it is about that time since the Rmoahals, the first sub-race of the Fourth Root Race who inhabited Atlantis, arose on a portion of the Lemurian Continent which at that time still existed. Remembering that in the evolutionary process the figure four invariably represents not only the nadir of the cycle, but the period of shortest duration, whether in the case of a Manvantara
or of a race, it may be assumed that the number of millions of years assignable as the life-limit of the continent of Lemuria must be very much greater than that representing the life of Atlantis, the continent of the Fourth Root Race. But in the case of Lemuria no dates can be stated with even approximate accuracy. Geological epochs, so far as they are known to modern science, will be a better medium for contemporary reference, and they alone will be dealt with.
