Extract

I am glad that my short article dealing with the occurrence of aragonite in the Middle Lias has evoked some interest. Professor Grenville Cole, who notices (with Mr. O. H. Little) this paper, has evidently delved deep, and I only hope that the publication of my preliminary note on aragonite in the Middle Lias has not prematurely precipitated that of his earlier research upon the matter from a more general point of view.
