Abstract
I AM pleased to have elicited the opinion of so distinguished an authority as Prof. Williamson upon Saporta and Marion's work, and his criticisms, even where antagonistic, will also, I am sure, be received by them with pleasure. Prof. Williamson holds views regarding the interpretation of some of the plant remains which are at variance with those held by most French geologists; but were the correctness of all his views conceded, I do not think Saporta and Marion's theory of the evolution of plants would thereby fall to the ground. A vast array of fact, which is not controverted, has been brought forward in a very able manner, and a connected and well-considered theory as to the nature of the modifications that have led through Cryptogams to Phanerogams is for the first time presented in a concise and lucid manner; and I think few will agree with the professor in deprecating such work because knowledge of the older floras is still incomplete.
