In previous communications, to the GEOLOGICAL MAGAZINE I have subjected the evidence as to the age of the Mammoth in the British Islands to criticism, and I ventured to conclude that whereever we can find the remains of the Mammoth and its contemporaries undisturbed and in situ, these remains are found under and not over or in the drift. This, so far as I know, is the case in every recorded instance where the Mammoth beds and the drift have been found superimposed upon each other. Let us now turn to the Continent and test the problem there. If we are to test it in the same way, which I take to be the only satisfactory way, namely, by evidence of superposition, we must naturally limit our survey to countries where the drift actually occurs. First, let us turn to Switzerland.
