II.—The Zones of the Oxford and Ampthill Clays in Buckinghamshire and Bedfordshire

Published online by Cambridge University Press:  01 May 2009

Extract

I have been studying the zones of the Upper Jurassic clays for the last seven or eight years. Repeated delays from various causes have already diminished the value of the results, and as the work is now held up indefinitely it seems advisable to publish a summary of the conclusions to which I have come, in case the completion of the work may fall to other hands. Such a summary must necessarily be much more dogmatic than I could wish. I have to acknowledge my very great indebtedness, both direct and indirect, in connexion with this work, to Mr. S. S. Buckman.
