For many years he furnished a scientific feuilleton to M. Gambetta's journal, "La République Française," The "First Year of Scientific Knowledge" has been translated into English, and is published by D. Appleton & Co. It is intended for children beginning to study science, and has probably no superior in suitableness for that purpose. It has proved an extraordinarily popular book in France, where it is said to have made the author's name known to a vast number of persons who knew nothing of his eminence either in science or in politics.

names four obvious sources of information regarding former conditions of the land: the testimony of historical documents; the names of places; tradition; and geological evidence. The historical testimony is not always direct, but is often very strong by incidental reference; and of this character are the allusions in poems and romances. Numerous local names which have now lost significance or seem inappropriate, are found upon analysis to have been descriptive, at the time, of the places on which they were conferred. So tradition, when well sifted, often throws light upon mooted points. Geological evidence is the best, the most accurate, the most lasting, and goes farthest back.

excellent maxims are given in a book on "The Ministry of Fine Art to the Happiness of Life," by Mr. Gambler Parry. On "The Purpose and Practice of Fine Art," the author says that "fine art comes of the union of love and labor, for without love it has no sufficient motive, and without labor it can have no success." The first step in a student's life, he adds, "is to divest his mind of all idea that genius can dispense with labor." A glaring fault of much of the work of the day is rebuked in the precept, "Of all the vices which pollute the source and thwart the progress of fine art, the striving after novelty is among the worst." Impatience and fickleness of purpose are condemned in "the genius most precious to mankind is continuous."
