more every year how much he has yet to learn," proceeds upon the opposite principle. Indeed, the author goes so far as to say that when teachers are ignorant they should not have any false pride or pretension about it, but should honestly and openly admit their ignorance. His language is, "When children ask their teacher for information on subjects with which he has little or no acquaintance, he should not be ashamed of frankly owning his ignorance." This is sensible talk, and those who like it will find much more of the same sort in the volume, which will furnish many hints worth the attention of practical teachers.
Mixed Essays. By Matthew Arnold. New York: Macmillan & Co. Pp. 347. Price, $2.
The name of this author is so well and favorably known as to make any commendation of his work on our part superfluous. He deals with modern questions in the spirit of liberal, often of radical criticism, and his opening discussions on "Democracy" and on "Equality," from the point of view of an independent English thinker, will have interest for intelligent American readers. The London "Athenæum" remarks of the volume: "One feels that these essays are Mr. Arnold, and that the lesson they convey as a whole is more precious than any single principle expressed throughout them. It is the lesson of courtesy, gentleness, and toleration. The stern practical nature of life in the nineteenth century and the controversial fierceness which is at once the strength and the misfortune of Englishmen could have no better foil than this high-souled preacher, who has continually reminded us, by his own example, of the supreme value of noble conduct and high demeanor."
