"There certainly is no deterioration in the quality of the books of the Standard Library. This book consists of short chapters upon natural history, written in an easy, fascinating style, giving rare and valuable information concerning trees, plants, flowers, and animals. Such books should have a wide circulation beyond the list of regular subscribers. Some will criticise the author's inclination to attribute the marvellous things which are found in these plants, animals, etc., to a long process of development rather than to Divine agency. But the information is none the less valuable, whatever may be the process of these developments." A GREAT SACRIFICE. Young's Analytical Concordance REDUCED TO $2.50, FOR A LIMITED TIME. Dr. Young cannot endure to have this, the great work of his life, judged by the unauthorized editions with which the American market is flooded. These editions, he feels, do his work and the American public great injustice. That Americans may be able to see the work as printed under his eye and from his own plates, he will sell some thousands of copies at A Great Pecuniary Sacrifice. The sale at the reduced prices will begin March 1, 1883, and will continue until the thousands of copies set apart for this sale are exhausted. This is the authorized, latest revised and unabridged edition--in every respect the same type, paper, binding, etc., as we have sold at the higher prices. It is a burning shame that the great life-work of one of the most eminent scholars, a work pronounced in both Europe and America as one of the most laborious and important that this century has produced, embracing nearly 1100 large quarto pages, each larger and containing more matter than Webster's Unabridged Dictionary, should prove a great financial loss to its author! This great work is selling in England at $9, and is now imported and sold in America at $2.50!! Orders will be filled in the order received up to the time of the exhaustion of the stock. Young's Great Concordance. DO NOT BE DECEIVED. There is but one _authorized and correct_ edition of Young's Concordance sold in America. _Every copy of this edition has on the title-page_ the words "Authorized Edition," and at the bottom of the page the imprint NEW YORK: FUNK & WAGNALLS. EDINBURGH: GEORGE ADAM YOUNG & COMPANY. All copies, no matter by whom sold, that have not these words printed on the title-page are printed on the bungling plates made by the late _American Book Exchange_. Dr. YOUNG says: "This unauthorized American edition is an outrage on the American public, and on me, containing gross errors." REV. DR. JOHN HALL says:
