Abstract
I HAVE only just read Prof. Newberry's clear and concise account of the American Cretaceous series (NATURE, vol. xxiv. p. 191). I regret that I am still unable to agree with him that the relative ages of American and European Cretaceous beds are satisfactorily correlated. I should not again venture to insist so strongly on what must seem to Dr. Newberry to be but an individual opinion, except that he seems to expect a reply, and I have further some new evidence to bring forward. Of my opinions the one to which he takes most exception seems to be that “no American or European so-called Cretaceous land flora can be proved to be as old as our White Chalk”. It is this statement therefore which I must substantiate.
