This is a book of blanks, for the botanical descriptions of plants as elucidated by the student in his analyses.

Signing the Document—The Laocoon of Labor—Chopping Sand—and other 'Essays. By Wheelbarrow. Chicago: "The Radical Review." Pp. 132.

The author of these essays assumes the name of "Wheelbarrow," he asserts, because he once labored with pick, shovel, and wheelbarrow on a railroad. He also states that he was once "clerk" to a brick-layer—that is, that he carried bricks for him. The series of essays was begun under prompting of the thoughts suggested by the telegraphers' strike of 1883; and most of them have grown out of other movements of working-men to better their condition. The burden of them is to expose the folly of the present management of those movements, and this is done in the most vigorous manner, whether it relates to trades-union despotism and exclusiveness, to the silver craze, or to any of the various tricks by which demagogues and monopolists, of whatever rank, seek to impose upon men who work—and all without hostility to any association for their real benefit. "In the present condition of society," says the author, "not to organize would be the very imbecility of resignation on the part of working-men. They may follow unwise principles for a time, but out of that organization a correct education will come at last."

A pleasant book of history, gossip, and anecdote, about the origin and development of railways in Europe and America. The statements of fact are derived from authentic sources, and the anecdotical serves to give variety to the solid part. The volume is illustrated by cuts of various engines and cars, including the earliest made, that give graphic representations of the modest originals from which the present provisions for the accommodation of travelers have been worked out.

Lessons in Chemistry. By William H. Greene, M. D. Philadelphia: J. B. Lippincott & Co. Pp. 357. Price, $1.25.

The author of the "Lessons" is Professor of Chemistry in the Philadelphia High School. He has prepared them upon the theory that the object of a limited course in chemistry is not to make chemists of the pupils, but to teach them what the science is, what it has accomplished, and what it may accomplish; and that the study of the science can be made attractive only by arousing natural curiosity as to the cause of the
