Cobb's FIRST BOOK, or INTRODUCTION TO THE SPELLING-BOOK, designed for the use of small children. This little work contains the Alphabet, and easy words of one, two, and three syllables, in which there are no double vowels or consonants, or silent letters, and only the long and short sounds of the vowels.

Cobb's SPELLING-BOOK, containing the Ru

diments of the English Language, arranged in catechetical order; an organization of the Alphabet; a greater number of spelling lessons than are generally inserted in Spelling-Books; many useful tables: and the proper names in the New Testament. Designed to teach the or thography and orthoepy of J. Walker.

"This Spelling-Book has peculiar claims to attention. Mr. Cobb might, we think, have done a signal service to education by publishing a corrected abridgment of Walker's Dictionary, or a vocabulary of disputed or doubtful words. He has evidently bestowed much attention on such subjects; and even his Spelling-Book wears a formidable air of authority from the labour and research by which it is characterized. The lessons are uncommonly full and accurate. The whole work, indeed, is highly creditable to the author's intelligence and industry.".-American Journal of Education.

"The author has certainly evinced great industry and research, and has shown himself well acquainted with the department in which he has so diligently laboured."-New York Times.

"Cobb's Spelling-Book is, we are confident, by far the most correct one at present to be found."-Cleaveland (Ohio) Herald.

"The plan and general arrangement of the book are probably the best which, in a mere Spelling-Book, can be adopted. It contains a greater number of words, and those more accurately classed in the several tables, than we have noticed in any other Spelling-Book."-Geneva Gazette.

"The whole arrangement of the lessons is more simplified, and better adapted to the capacity of the child, than that of the books in general use."-Catskill Recorder.

"Its correctness of spelling and pronunciation, the excellent arrangement and extensive number of words, render it a most interesting work." -Montrose (Pa.) Gazette.

"The classification of words is judicious, and the tables are systematically arranged."—Le Roy Gazette.

"The author seems to have stripped the work, as much as possible, of all perplexity. His rudiments are simple and comprehensive. His les gons are well arranged, and composed of words most admirably selected." -Fredonia Censor.

Cobb's Abridgment of J. Walker's CRITICAL

PRONOUNCING DICTIONARY. In this Dictionary, Mr. Walker's principles of orthography and pronunciation are strictly followed; and, in addition, each word is systematically divided; the secondary accent noted; the plurals of nouns, the present tense and preterit of verbs, the participles, and the variable adjectives, are inserted; and all useless repetitions of words are avoided; to which are prefixed, concise Principles of Pronunciation, and rules for accentuation and the division of words: with an Appendix, containing a class of words which are in common use in this country, and not found in Walker's Dictionary. "Mr. Cobb has recently published, an Abridgment of Walker's Dictionary, in the usual size and form of Dictionary abridgments. We have given the work some attention, and found it, in many important respects, superiour to those that are in ordinary use. The plurals of nouns are given, and the preterits and participles of verbs; the words are all divided into syllables, and, for the first time in any Dictionary, have the mark of the secondary accent."-U. S. (Philadelphia) Gazette.

"Cobb's Dictionary has been put into our hands lately, and upon a cursory examination, we have found it to be a compilation made with care and accuracy. The author has adopted the pronunciation of Walker throughout, as found in the London editions. We must still think it is entitled to the preference over any other. As a standard of orthoepy, we are decisively of opinion, after long attention to the subject, and much investigation, Walker's system is preferable to any other that has appeared either this side the Atlantick or the other. Mr. Cobb's Dictionary contains the plurals of nouns and the preterits of verbs, as forming an additional syllable by the addition of s or es, &c. To these are added, the participles and adjectives, which will occasionally be found convenient." -New York Evening Post.

"Mr. Cobb's School Dictionary seems calculated to be very useful to children and foreigners learning the language. He has followed Walker, and made his compilation from the best London editions; adding the plurals of nouns and preterits of verbs, the participles and variable adjec tives, &c. all which, to foreigners especially, must obviously be of great service."-New York Commercial Advertiser.

"Its superiority in the particulars we have named, gives the work decisive advantages for the use of schools, and as a help to foreigners who may be learning the English language."-New York Atlas.

"This work has been compiled apparently with great care. Several instances of improvement might be adduced, which render this work valuable."-New York Morning Herald.

"We are thus particular in our notice of this work, because the subject is of importance, and because we believe the abridgment to surpass many others, if not all others, which have preceded it, and which are now in use. "We avail ourselves of this occasion to say, that our language and all such as feel an interest in the prevalence of correct orthography and orthoepy, and especially such as desire to give young minds a right direc tion in these respects, owe much to the author of this abridginent."— Albany Argus.

"Besides the orthography and pronunciation of Walker, the compiler has given the plurals of nouns, the present and preterit of verbs and made some other additions, which can not fail to be beneficial to the learner."-Philadelphia Post.

Cobb's JUVENILE READER, No. 1; containing interesting, moral, and instructive Reading Lessons, composed of easy words of one and two syllables. Designed for the use of small children in families and schools.

"The author of a well known edition of Walker's Dictionary has pub. lished the first No. of a book called the Juvenile Reader. The work is intended to lead the child by an easy gradation from easy to difficult readings, and the lessons are selected from authors of reputation."-New York Evening Post.

"We have before us a neat little manual bearing the above title. It is the first of a series of reading books for children, containing interesting, moral, and instructive reading lessons, composed of easy words of one and two syllables.' Mr. Cobb is advantageously known as the author of an excellent Spelling-Book, and School Dictionary, and is eminently qualified to compile elementary works for youth. Mr. Cobb very properly discards the plan of placing dialogues between brutes before children, as he conceives they are destitute of truth, and contrary to the principles of nature and sound philosophy."-New York Evening Journal.

"From a glance at this work, which we have thus far been only able to give it, we deem it one worthy of commendation."-New York Mercantile Advertiser.

"Mr. Cobb's Juvenile Reader, No. 1, is executed in a very pretty and appropriate manner, with distinct typography, and on fine paper. It is also embellished with a few cuts, which will give it attractions for the youthful class, in reference to whose wants it has been prepared. But its higher characteristicks, in its adaptation of style and language to the uses for which it was designed, are those which lead us to mention the impretending little volume. Its peculiarities consist mainly in such a selection of words, that none may be beyond the comprehension or the orthoepick skill of children just beginning to read; so that they may enter on this acquirement with the fewest possible obstacles; and their progress being thus facilitated, they may the more easily gain a fondness for an art, the possession of which lies at the very foundation of most branches of useful knowledge."-New York Atlas.

"Cobb's Juvenile Reader, No. 1, is the first number of a series of small books, designed to aid children in their first essays at reading, by L. Cobb, author of a Spelling-Book, and other works for instruction. The aim of the author appears to be, to lead the young reader by easy and regular gradations, from simple to complex sentences, graduating at every stage, the subject, matter, and the style, to the advancement of the pupil's understanding. The importance of such a course of reading, to most children, must be obvious. A very common errour, in all books of this class, which have fallen under our inspection, is, that polysyllables are copiously introduced, into even the earliest reading lessons, and the language is too elevated for juvenile comprehension. The natural effect is, that the reading of the child is purely mechanical; he learns to read words without connecting ideas with them, and the consequence to the child can not be misconceived.

"The author of the Juvenile Reader seems to have avoided these errours, while he has given to the child a neat and interesting little volume, from which he can not fail to derive important lessons in morality. One feature of this work, strikes us to be of great importance: 'That in the course of the numbers, all the words of variable or doubtful orthography in the English language will be given.'"-Truth Teller,

Cobb's JUVENILE READER, No 2.; containing interesting, moral, and instructive reading lessons, composed of words of one, two, and three syllables. Designed, in connexion with No. 1., to accompany the Spelling-Book. Cobb's JUVENILE READER, No. 3.; containing interesting, historical, moral, and instructive reading lessons, composed of words of a greater number of syllables than the lessons in Nos. 1 and 2; and a greater variety of composition, both in prose and poetry, selected from the writings of the best American and English authors. With Observations on the Principles of good Reading.

"COBB'S JUVENILE READER, Nos. 1, 2, and 3. These little volumes, together, form a series of elementary reading books, graduated to the capacities and tastes of children. The writer has been at some pains to arrange the different lessons in such a manner, that each preceding one shall prepare the pupil for the one that follows-both as to orthography and subject."-New York American.

"We are not aware of any reading book, for beginners in schools, in which the number of syllables is limited as in the first and second numbers of this work."-New York Evening Post.

"These books will become valuable in our schools, where primary in. struction is going on."-New York Evening Journal.

"We think very favourably of this work, both as regards manner and matter."-New York Mercantile Advertiser.

"The first book will be a valuable auxiliary to the little curly-headed and rosy-cheeked gentlemen.

The second book is adapted to children of a more advanced age.

The third claims a more serious notice. In it much instruction in the elements of natural philosophy and history is conveyed to the more advanced and intelligent reader. The brief chapters on the dog, alum, cork, the horse, heat, licorice, and light, are precisely the kind of composition to be placed in the hands of youth."-New York Mirror.

"Messrs. Collins & Hannay have published Cobb's Juvenile Reader, designed for the use of small children, in families and schools. It ap pears to be well adapted for the purpose."-N. Y. Courier & Inquirer. "The books are the best that have come to our knowledge."-N. Y. Sentinel.

"The Juvenile Reader consists of a series, in three numbers, adapted to the different ages of the learner. It is due to Mr. Cobb, to add, that in this branch of instruction, so essential to the subsequent progress of the pupil, as well as in his works of a higher grade, such as his SpellingBook and Dictionary, this community stand greatly indebted to him for his indefatigable exertions, and for the assiduous application of practical and useful talents."-Albany Argus.

2, and 3, con"We have received COBB'S JUVENILE READER, Nos. taining progressive lessons. In the little volumes before us, Mr. C. has, in addition to a judicious selection of subjects, and progressive arrange. ment of words, been careful to introduce many words most liable to be misspelled. With these advantages, Mr. Cobb's books may claim a place in our primary schools, upon the tenable ground of usefulness."-U.S. (Philadelphia) Gazette.

Notwithstanding the great improvement which, of late years, has taken place in children's books, there was still a want of elementary works, of a proper description, and the one before us, which seems well calcula. ted to supply the deficiency, must be found very useful."—American (Boston) Traveller.
