128 of the superlative literary merit of the tragedy, but also for the editor's excellent critical introductions, in which he gives an account of the growth of the legend of Iphigenia, an analysis of the plot and artistic structure of the work, and a dissertation on the meters and technique. The volume is one of the publishers' "College Series of Greek Authors," edited under the supervision of J. W. White and T. D. Seymour. Pp. 197. Price, $1.50.—Mr. Addison Hague's Irregular Verbs of Attic Prose gives, after the regular verbs, pure, mute, and liquid, the irregular verbs in alphabetical order, with prominent meanings and special uses of frequent occurrence, often illustrated by translated examples, the most important compounds, many related words, and some four hundred and fifty English derivatives. The volume constitutes a helpful bridge over a most difficult passage in the study of Greek. Pp. 268. Price, $1.60.

Prof. S. E. Tillman's Elementary Lessons on Heat (J. B. Lippincott Company) have been prepared to meet the necessities of a short course of seventy hours at the United States Military Academy. The selection of material has been guided by considerations of the sub-course of studies and of what is essential and most useful for the students to know. A logical arrangement is sought, and clearness and conciseness in relation are aimed at. Most of the experimental illustrations described or referred to are such as can be performed in the lecture-room. The special topics treated of are "Thermometry," "Dilatation of Bodies," "Calorimetry," "Production and Condensation of Vapor," "Change of State," "Hygrometry," "Conduction," "Eradiation," "Thermo-Dynamics," and the "Meteorological Aspects of Heat." Pp. 160. Price, $1.80.

The Manual of Chemistry for the Use of Medical Students of Dr. Brandreth Symonds (P. Blakiston, Son & Co., Philadelphia) is not designed to be a medical chemistry, but takes up those parts of general chemistry which it is necessary for medical students to know. The author, having prepared students for several years in this branch, believes that he knows their needs, and has made this effort, in the light of that knowledge, to supply them. Besides the elements, a large share of the space is allotted to the chemistry of water and air and the substances by which they are polluted; and for this acknowledgment is made to the lectures and articles of Prof. C. F. Chandler. A chapter is given to the tests for the important substances, and another chapter to the tests for urine and the substances that occur in it. The theories of to-day concerning chemical action are briefly presented. The metric weights and measures are also noticed, and the rules are given for converting degrees of temperature. Pp. 154. Price, $2.00.

The Kingdom of the Unselfish; or, the Empire of the Wise (Empire Book Bureau, 28 Lafayette Place, New York), has been written by Mr. John Lord Peck with reference to the existing stage of social evolution. If not suited to the present state of opinion, it may find a reading in the next century. The purpose of the book is unfolded in the introductory chapter, which is headed "The Reliable and Unreliable in Thought." Of the unreliable are all religious systems founded on tradition and revelation, dogma, and speculative philosophy, including all the systems that have followed one another from Plato and the ancients down to the pessimism of Schopenhauer and Hartmann and the agnosticism of Comte, Huxley, and Spencer. Neither of these last systems "is sufficiently near the final truth to long satisfy the human mind, and the prediction is here ventured that both of them will give way to a system of ontology
