THE PLEISTOCENE DEPOSITS OF EAST ANGLIA. 
BY F. W. HARMER, F.G.S. 
I have the pleasure of exhibitmg to-night tlie first maps 
of the Glacial deposits of this, or I think of any other district, 
ever attempted on a similar scale, constructed by the distin- 
guished man with whom I had the privilege of working so long. 
The first was published by him in 1865, the result of a preliminary 
examination of East Anglia during several years immediately 
preceeding ; the second was drawn, together with more than 
a hundred miles of sections, for the meeting of the British x\ssocia- 
tion in Norwich in 1868, and although the survey on which it 
was founded had not then been completed, it represents generally 
what I still believe to be the geological structure of this district. 
The third appeared in 1872, in the " Supplement to the Mollusca 
of the Crag."* It should not be forgotten that Searles V. Wood, 
Jun., was a pioneer, and it does his memory no discredit to 
admit that some of his work may require reconsideration in the 
light of our present knowledge. Although the Glacial deposits 
of East Anglia have engaged the attention of geologists for many 
years, and much has been written thereon, they still present 
problems waiting solution. I therefore cordially welcome this 
visit of your Society to Norfolk, and hope that, bringing to the 
study of our drifts an intimate knowledge of those of other 
districts, you may be able to throw light on some matters as to 
which we are still in doubt. 
I have been asked to open a discussion on " The relation 
of the Glacial beds of East Anglia to those of the North of 
England," but, indeed, as to this, I am more anxious to hear 
your opinion than to express my own. I have recently published, 
moreover, a resume of my views on East Anglian geology, which 
some of you may have read.f Briefly restating my opinion as to 
the conditions which may have obtained in this region during
