Several members having suggested to me the desirability, in these days of Zeppelin possibilities, of bringing before the Society an account of some of the additions to our knowledge of Wealden geology, which have accumulated during recent years, especially recently, before they are lost; I trust what I have to offer will prove of interest. Personally I would rather have waited until I had been able to work out thoroughly the Lenham-Diestian fauna, and have followed up certain of the fluviatile beds; but unfortunately this may mean years: there is another reason why all this should be widely known, and that is there is a growing tendency in certain quarters to minimize the age of the Crag beds, and to regard them as the marine equivalents of the landward Pleistocene river drifts. This of course reduces both the antiquity and value of the subglacial and sub-Crag discoveries in East Anglia, of which the members of the Society are naturally jealous.
