ELEMENTARY ALGEBRA FOR

SCHOOLS.

Sixth Edition. Globe 8vo. 3s. 6d. ; with Answers, 4s. 6d. ATHENEUM:-"A work of exceptional merit."

NATURE:-"This is, in our opinion, the best Elementary Algebra for school use. It is the combined work of two teachers who have had considerable experience of actual school teaching. and so successfully grapples with difficulties which our present textbooks in use, from their authors lacking such experience, ignore or slightly touch upon. We confidently recommend it to mathematical teachers, who, we feel sure, will find it the best book of its kind for teaching purposes."

...

ACADEMY:-"We will not say that this is the best Elementary Algebra for school use that we have come across, but we can say that we do not remember to have seen a better... It is the outcome of a long experience of school teaching, and so is a thoroughly practical book.... Buy or borrow the book for yourselves and judge, or write a better."

KEY. Crown 8vo. 8s. 6d.

HIGHER ALGEBRA. A Sequel to Elementary Algebra for Schools. Third Edition, revised and enlarged. Crown 8vo. 78. 6d.

*** The third edition contains a collection of three hundred Miscellaneous Examples which will be found useful for advanced Students. These examples have been selected mainly from recent Scholarship or Senate House papers.

ATHENÆUM:-"We unhesitatingly assert that it is by far the best work of its kind with which we are acquainted. It supplies a want much felt by teachers."

ACADEMY:- -"... Is as admirably adapted for College students as its predecessor was for schools. It is a well-arranged and wellreasoned-out treatise, and contains much that we have not met with before in similar works. The book is almost indispensable and will be found to improve upon acquaintance."

SATURDAY REVIEW:-" They have presented such difficult parts of the subject as Convergency and Divergency of Series, Series generally, and Probability with great clearness and fulness of detail.

No student preparing for the University should omit to get this work in addition to any other he may have, for he need not fear to find here a mere repetition of the old story.'

ALGEBRAICAL EXERCISES AND EXAMINATION PAPERS. To accompany "Elementary Algebra." Third Edition, revised and enlarged. Globe 8vo. 2s. 6d.

SATURDAY REVIEW:-"To the exercises, one hundred and twenty in number, are added a large selection of examination papers set at the principal examinations, which require a knowledge of algebra. These papers are intended chiefly as an aid to teachers, who no doubt will find them useful as a criterion of the amount of proficiency to which they must work up their pupils before they can send them in to the several examinations with any certainty of success."

IRISH TEACHERS' JOURNAL:-"We know of no better work to place in the hands of junior teachers, monitors, and senior pupils. Any person who works carefully and steadily through this book could not possibly fail in an examination of Elementary Algebra.... We congratulate the authors on the skill displayed in the selections of examples."

ARITHMETICAL EXERCISES AND EXAMINATION PAPERS. With an Appendix containing Questions in LOGARITHMS AND MENSURATION. Second Edition. Globe 8vo. 2s. 6d.

CAMBRIDGE REVIEW:-"All the mathematical work these gentlemen have given to the public is of genuine worth, and these exercises are no exception to the rule. The addition of the logarithm and mensuration questions add greatly to the value."

EDUCATIONAL TIMES:-"The questions have been selected from a great variety of sources: London University Matriculation; Oxford Locals-Junior and Senior; Cambridge Locals-Junior and Senior; Army Preliminary Examinations, etc. As a preparation for examination the book will be found of the utmost value."

A TEXT BOOK OF EUCLID'S ELEMENTS. Including Alternative Proofs, together with additional Theorems and Exercises, classified and arranged. By H. S. HALL, M.A., and F. H. STEVENS, M. A., Masters of the Military and Engineering Side, Clifton College. Globe 8vo. Book I., 1s.; Books I. and II., 18. 6d.; Books I.-IV., 3s.; Books III. and IV., 2s.; Books III.-VI., 3s.; Books V., VI. and IX., 2s. 6d.; Books I.-VI. and XI., 4s. 6d.; Book XI., 18. A KEY to Books I.-IV. 6s. 6d. CAMBRIDGE REVIEW:-"... The whole is so evidently the work of practical teachers, that we feel sure it must soon displace every other Euclid."

JOURNAL OF EDUCATION:-"The most complete introduction to Plane Geometry based on Euclid's Elements that we have yet seen.' PRACTICAL TEACHER:-" One of the most attractive books on Geometry that has yet fallen into our hands."

IRISH TEACHERS' JOURNAL:-"It must rank as one of the very best editions of Euclid in the language."
