The _Bulletin from the Laboratories of Natural History of the State University of Iowa_, Vol. IV, No. 3, contains two technical articles: On the Actinaria, collected by the Bahama Expedition of the University, in 1891, by J. P. McMurrich, and the Brachyura of the Biological Expedition to the Florida Keys and the Bahamas in 1893, by Mary J. Rathbun; and a list of the coleoptera of Southern Arizona, by H. F. Wickham. Mr. Wickham observes that the insects of northern Arizona are widely different from those of the southern part, a fact which he ascribes to difference of altitude, and, consequently, in vegetation. The Bulletin is sold for fifty cents a copy. Two books in English--_Elementary English_ and _Elements of Grammar and Composition_--prepared by _E. Oram Lyte_, and published by the American Book Company, are intended to include and cover a complete graded course in language lessons, grammar, and composition for study in the primary and grammar grades of schools. The endeavor has been made to present the subject in such a way that the pupil shall become interested in the study from the first. The first book, Elementary English, is designed to furnish material for primary language work, and to show how this material can be used to advantage, embodying and representing the natural methods of language teaching. The child is given something to do--easy and practical--at every point, and is not troubled by formal definitions and rules to be committed to memory. The second book is also based on the principle that the best way to gain a working knowledge of the English language is by the working or laboratory method. It is therefore largely made up of exercises, and aims to teach through practice. The subject is unfolded from a psychological rather than a logical point of view. What is to be memorized is reduced to a minimum, and not presented till the pupil is ready for it. The lessons in literature and composition are designed to help the pupil to appreciate worth and beauty of literature, and lead him to fluent and accurate expression. _The Bulletin of the Geological Institution of the University of Upsala_ presents a series of special papers of much interest to students of that science, on studies in geology, largely of Scandinavia, but of other countries as well. Part 2 of Vol. III, now before us, has such papers on Silurian Coral Reefs in Gothland, by Carl Wiman; the Quaternary Mammalia of Sweden, by Rutger Sernander; Some Ore Deposits of the Atacama Desert, by Otto Nordenskiold; the Structure of some Gothlandish Graphites, by Carl Wiman; the Interglacial Submergence of Great Britain, by H. Munthe; Mechanical Disturbances and Chemical Changes in the Ribbon Clays of Sweden, by P. J. Holmquist; Some Mineral Changes, by A. G. Högborn; and the Proceedings of the Geological Section of the Students' Association of Natural Science, Upsala. The articles are in German, English, and (in previous numbers) French.
