Is a well-nigh indispensable requisite for every lawyer, clergyman, and other professional man, as well as every intelligent family. It contains 10,000 WORDS and MEANINGS not found in other Dictionaries. It is now believed to be by far the most complete, useful, and satisfactory Dictionary of the language ever published, as it is by far the largest single volume ever issued in any language. The possession of any other English Dictionary, or any previous edition of this, can not compensate for the want of this very full and complete one. In its present perfected state it must long remain the BEST ENGLISH DICTIONARY, and, once possessed, remain of constant and abiding value. No other English Dictionary has such weight of authority, or is cited so frequently in Legislatures, Courts of Justice, or in determining the meaning of contracts, as Webster. A very large number of Reported Cases, arguments of counsel, &c., might be quoted to prove this. "Unquestionably the very best Dictionary of our language extant. Its great accuracy in the defi nition and derivation of words gives it an authority that no other work on the subject possesses. It is constantly cited and relied on in our Courts of Justice, in our Legislative bodies, and in public discussions, as entirely conclusive."-Hon. John C. Spencer. Lately one of the most important suits of modern times, in the highest court of England, turned solely on the definition of a single word. It is significant of Dr. Webster's reputation in England as a definer of words, that, in the Alexandra case, tried in the Court of Exchequer, at Westminster Hall, under purely English law, no other Dictionary, English or American, was quoted or alluded to than his. We quote from the Lord Chief Baron's decision, June 24, 1863, (page 232 of the report of the trial): I have looked, so that I might not go wrong, (as we have the advantage of having it here,) at Webster's American Dictionary, a work of the greatest learning, research, and ability." "I think it not only a great improvement upon former issues of the same work, but superior, in most respects, to any other English Dictionary known to me. The labors of the recent editors and contributors have made it undoubtedly the best general etymologicon we yet possess of the language; its vocabulary is as ample as could well be given in the compass of a single volume; its definitions are, in general, sufficiently exact and discriminating; and its pronunciation is apparently conformable to the best usage."-Hon. George P. Marsh, Florence, Italy, March 7, 1866. "Etymological part remarkably well done... We have had no English Dictionary nearly so good in this respect."-North American Review. "In our opinion, it is the best Dictionary that either England or America can boast."-National Quarterly Review. "No English scholar can dispense with this work."-Bibliotheca Sacra. "In its general accuracy, completeness, and practical utility, the work is one which none who can read or write can henceforward afford to dispense with."--Atlantic Monthly. "The NEW WEBSTER is glorious-it is perfect-it distances and defies competition -it leaves nothing to be desired."-J. H. Raymond, LL. D., President of Vassar College. "All young persons should have a standard Dictionary at their elbows. And while you are about it GET THE BEST; that Dictionary is NOAH WEBSTER'S- the great work, unabridged. If you are too poor, save the amount from off your back, to put it into your head."-Phrenological Journal. "Every farmer should give his sons two or three square rods of ground, well prepared, with the avails of which they may buy it. Every mechanic should put a receiving box in some conspicuous place in the house to catch the stray pennies for the like purpose. Lay it upon your table by the side of the Bible; it is a better expounder than many which claim to be expounders. It is a great labor saver; it has saved us time enough in one year's use to pay for itself; and that must be deemed good property which will clear itself once a year. If you have any doubt about the precise meaning of the word clear, in the last sentence, look at Webster's nine definitions of the v. t."-Massachusetts Life Boat. In One Volume of 1,840 Royal Quarto Pages, and in various Common and Fine Bindings. "GET THE BEST." "GET THE LATEST." "GET WEBSTER." Published by G. & C. MERRIAM, Springfield, Mass.

WILLIAM B. ROGERS, President. [The following paper, on a subject of the greatest importance to all students and teachers, was read at a recent meeting of the American Academy of Arts and Sciences, by that eminent oculist, Dr. Henry W. Williams, of Boston. The subject was afterwards discussed by the President of the Academy Prof. Gray, by Prof. Lovering, President Rogers and others, all of whom agreed as to its importance. We are happy in being able to state that Dr. Williams has consented to read a paper on the care of the eyes at the meeting of the State Teachers' Association, in October.] To many it will doubtless be a matter of no little surprise that a condition of vision in which they had rejoiced as giving them advantages above other men, and of which, from long habituation, they have scarcely felt the inconveniences, is a state fraught with danger to the most important of the senses. Never having known perfect vision at a distance unless aided by glasses, they had believed themselves compensated, in their almost microscopic powers as regarded minute details of near objects, and in the hope that they could continue to read without spectacles long after the period of life when their friends would be compelled to assume them. To be told that they have laid but a flattering unction to their souls, that they are subjects of a serious infirmity, and that their children may probably inherit such a predisposition as require careful management of their eyes to avert danger of ultimate blindness is to them, a far from welcome announcement. Were this state of things inevitable, were the condition to affect merely the individuals who had acquired it, or were the inherited tendency such as could only be obviated or alleviated by the resources of professional art, there would be no propriety in calling the attention of this Academy to the subject. But as the evil is increasing in rapid progression, as it threatens to entail a vast amount of disappointment and misery on those educated classes whose eyes are, or ought to be, of most personal and public value, and as our system of education is in a measure responsible for the mischief it creates and perpetuates, it becomes a serious question what should be done to arrest the downward tendency; for, if the condition in prospect is to be one of the necessary concomitants of a high civilization, the latter would be purchased at almost too high a price. It has been well known that in all countries near-sight is met with most frequently among the studious classes, while it is comparatively rare among the peasantries, as also among sailors and savages. But it is only of late years that this fact and the causes on which it depends have been satisfactorily explained. That they may be fully understood, and their important bearing properly estimated, it will be necessary to say a word as to the conditions of the eye-ball which produce near-sightedness, favor its increase, and involve subsequent secondary affections of vision. Instead of being a round globe, like the normal eye, a myopic eye has more or less of an ovoid shape, having a long arteroposterior diameter. Parallel rays of light, coming from distant objects are therefore brought to a focus before they reach the surface of the retina, and a distinct image can be formed only by the aid of a concave glass placed before the eye to modify the direction of the rays which enter it. The larger part of this elongation takes place at the expense of the posterior half of the eyeball, and when the globe is pressed upon by its motor muscles, as occurs during the action of conver gence associated with the accommodation of the eyes in looking at |
