In consequence of these oscillations in the climatic conditions of the Drift Era as a whole, we have to distinguish the Preglacial Era and the Interglacial Era, as warmer sub-periods of the Drift, from the real Glacial Periods. The latter appear as a first, or earlier, and a second, or later Glacial Period, as remains of which the zone of the older moraines and the zone of the later ones clearly mark the limits of the former glaciation.
