We have often wondered why such a work as this was never undertaken. Commissioner Le Due deserves great praise for it. It gives a value to the Reports of the Department almost incalculable.

The American Naturalist for November is a remarkably full and interesting number. It has improved greatly during the past year in the amount of general information it gives to the reader. In some of the departments this is particularly noticeable - in botany, however, less than in some others. It is well to give attention to long papers giving "original " views, but the "general information" column, which requires much patient editorial research and hard work, is generally badly served in most scientific papers, and it is pleasant to note the improvement here in this. McCalla & Stavely, Philadelphia, are the publishers, and Dr. Packard, we believe, the chief editor.
