The United States Geological Survey has issued a paper, by Professor R. S. Tarr, of Cornell University, on the Physiography and Glacial Geology of the Yakutat Bay Region of Alaska. Here we have high coastal ranges, culminating in Mounts Cock and Seattle, from which descend great glaciers to the sea, and also other glaciers which come down to the waters of Russell Fiord. The whole region shows signs of intense glaciation during quite recent times, and on this account is an admirable area for the study of glaciers and their work.

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.
