 voted exclusively to its interests. America, too, contributed largely to the Geologic Congress recently held in London, and it is pleasing to note that the next session of the Congress is promised for Philadelphia.

At the suggestion of one of our associates I call the attention of the students of the science, and indeed all interested in it, and also of Geographers, to a recent publication entitled, "The Building of the British Isles," by Jukes-Browne (Scribner & Welford, N. Y.). It has been characterized as the best treatise on the evolution of the land areas which has yet appeared; from the Geologist point of view it is the book of the year. Another associate recommends to most attentive consideration the recent articles on "Three formations of the Middle Atlantic slope," by W J McGee (Am. Journal Science, Feb.-June, 1888), as one of the most original essays of recent years.

It also gives me great pleasure to bring to your attention an article on the "Physical Geography of New England," by Wm. M. Davis, in a book on the "Butterflies of New England," by S. H. Scudder. It is hardly necessary to recommend this publication to your perusal, as I doubt not being from the pens of our Associates, it will excite a lively interest in those devoted to these sciences.

In conclusion permit me to refer briefly to the "National Geographic Magazine," published by the Society, the first number of which has recently been placed before you. It is the desire of the Committee having charge of this publication to make it a journal of influence and usefulness. There is abundant material in the Society to furnish the substance, if those who have it at command will make legitimate use of their opportunities. It would be unfortunate if the text should be confined to the papers presented to the Society. It was not the intention of the Board of Managers that such should be the case, when the publication was determined upon. On the contrary, it was the expectation that there would be original communications from many sources: essays, reviews and notes on the various subjects of the five Departments in which the Society is organized, not necessarily from the members, but also from their friends interested in these divisions of the general subject. While this expectation has been realized in a measure, there is room for improvement and it is hoped the future will show an increasing interest and more generous contributions.
