INTRODUCTION. 
 
 A list of reference books in Physics was published by the 
 Association six years ago, through a conviction that a refer- 
 ence library for pupils and teachers should be available in 
 connection with the work in Physics in the secondary schools. 
 Owing to the rapid development of the science, the changes 
 in theories and methods of presentation, as well as the great 
 number of new books published in this department of science, 
 a complete revision was ordered by the Association to meet 
 present needs. 
 
 In making the revision this committee is deeply indebted 
 to the former committee under the chairmanship of Charles 
 R. Allen for the general plan of the work. Many books in- 
 cluded in the earlier list have now been omitted as less val- 
 uable than later books, or because out of print. Many later 
 publications have been added. 
 
 The list is primarily designed to be a guide and help to the 
 teacher in selecting his reference library. The conditions and 
 nature of the instruction in science vary so widely in different 
 schools that it has seemed best to make the list quite com- 
 prehensive, trusting that the appended comments may enable 
 a teacher to select those books most suited to his special needs. 
 While the principal list includes essentially books of reference 
 for secondary schools, there have been added the following 
 minor lists : 
 
 (.a) A title list of the more recent high school text- 
 books of Physics, with their publishers. 
 
 (b) A list of the addresses of some of the more important 
 publishers of scientific books. 
 
 (c) A list of books costing $30, which would constitute 
 a valuable nucleus for a library. 
 
 (d) A second list of books costing $30, which, with the 
 above list, would constitute a valuable and economical working 
 library.

Introduction 
 
 Under each title is given data regarding size, price, date, 
 publisher, etc., and a comment by some member familiar with 
 the book, which is intended to enable teachers to judge of its 
 availability for his special needs. 
 
 Thanks are due to members of the Association for their 
 co-operation, and to publishers for courteous assistance. If 
 this work may prove an aid in promoting the efficiency of the 
 work in Physics in secondary schools, the object of its publi- 
 cation will have been attained. 
 
 The Secretary of the Association will give any information 
 desired in regard to obtaining any further copies of this list.

GENERAL TREATISES. 
 
 Text-Book of General Physics. 
 
 Author, Joseph S. Ames, Ph.D. Published by American 
 Book Company. Size, 5 1-2 in. x 8 1-4 in. Pages, 768. 
 Date, 1904. Price, $3.50. 
 
 A thoroughly modern college text-book designed (a) to give a 
 concise statement of the experimental facts on which the science 
 of Physics is based and (b) to present the accepted theories, which 
 correlate and explain these facts. It is one of the most satisfactory 
 books for general teachers' reference. Parts of it are too 
 mathematical for secondary students, but many portions are 
 entirely within range of the pupil's study. Very little attention 
 is given to the familiar applications of the principles enunciated. 
 There are about 300 cuts. 
 
 Physics. 
 
 Edited by George A. Barker. Published by Henry Holt & 
 Co. American Science Series, Advanced Course. Size, 
 5 1-2 in. x 8 3-4 in. Pages, 902. Date, 1892. Price, $3.50. 
 
 A general treatise written from the standpoint of matter and 
 ether. All the phenomena of physics are considered as due to 
 the condition of matter and ether stress. Geometry and trigonom- 
 etry are used to some extent. Illustrations rather few, mainly dia- 
 grammatic. Little general description of experiments or apparatus. 
 
 University Physics. 
 
 Author, H. S. Carhart. Published by Allyn & Bacon, Bos- 
 ton. Size, 7 1-2 in. x 5 1-2 in. Price, per vol., $1.50. Vol. 
 I, Topics: Mechanics, Sound and Light. Revised and re- 
 written edition, 1906. Pages, 346. Vol. II, Topics: Heat 
 Electricity and Magnetism. Revised and rewritten edition, 
 1904. Pages, 456. 
 
 This is a comprehensive treatment of the principles of Physics, 
 a descriptive work covering the whole ground. A fair knowledge 
 of algebra, geometry and trigonometry would be needed for an 
 intelligent understanding of many of the discussions. There is 
 very little description of experiments and the majority of the illus- 
 trations are diagrammatic. It contains but few references to appli- 
 cations of principles either by descriptions or by problems. The 
 major part of the book would be above the average secondary 
 school pupil, but it is an excellent reference book for any one 
 having the necessary mathematical knowledge. 
 
General Treatises 
 
 Ganot's Physics. 
 
 Atkinson's translation. Published by William Wood & Co., 
 New York. Size, 8.5 in. x 6 in. Pages, 1,169. Date, 17th 
 edition, enlarged, 1905. Price, $5.00. 
 
 This is a general treatise on the principles and applications of 
 Physics. It corresponds closely in its arrangement to the average 
 secondary school text-book. It contains many illustrations of 
 apparatus and descriptions of experiments. The treatment is 
 mainly non-mathematical. The appendix contains a number of 
 problems. Very little of it should be beyond the grasp of a sec- 
 ondary school pupil. This last edition is one of the most satisfactory 
 descriptive treatises for general reference. 
 
 Practical Physics. 
 
 Author, Glazebrook & Shaw. Published by Longmans, 
 Green & Co. Size, 7 in. x 4 1-2 in. Pages, 689. Date, 
 1905, revised, enlarged. Price, $2.50. 
 
 A thorough book in which the facts are put clearly and with 
 mathematical exactness. It is on the whole too difficult for secondary 
 school pupils. It was written for the assistance of teachers and 
 advanced students in physical laboratories, and is worthy of their 
 attention. It covers the whole range of subjects in physics. It 
 contains many mathematical formulae and 134 wood 'cuts. 
 
 General Physics. 
 
 Authors, Charles S. Hastings, Ph.D., and Frederick E. 
 Beach, Ph.D., of Yale University. Published by Ginn & Co., 
 Boston. Size, 6 in. x 8 1-2 in. Pages, 768. Date, 1899. 
 Price, $2.75. 
 
 This book is developed from the idea that an understanding of 
 energy is absolutely essential to the subject and that elementary 
 mechanics must be regarded as the logical basis of the whole sci- 
 ence of Physics. Hence the treatment of Mechanics is more com- 
 plete than is ordinarily the case. The continuity of the science is 
 emphasized. 
 
 To read this book, a working knowledge of trigonometry is nec- 
 essary. Deserving of. special notice are the chapters on Change 
 of State, Thermodynamics, Kinetic Theory of Gases, Electric Fields 
 and Electric Waves. The cuts (495) are new, well executed and up 
 to date. The tables of constants are numerous and complete. 
 Many problems are appended to the various chapters. Designed 
 to be a college text-book. 
 
General Treatises 
 
 The Elements of Physics. 
 
 Authors, Edward L. Nichols and William S. Franklin. 
 Published by The Macmillan Co. Size, 6 in. x 9 in. Nu- 
 merous illustrations. Vol. I, Mechanics and Heat. Pages, 
 290. Revised, 1903. Price, $1.90. Vol. II, Electricity and 
 Magnetism. Pages } 303. Entirely rewritten. Price, $1.90. 
 Vol. Ill, Light and Sound. Pages, 262. Rewritten. Price, 
 $1.50. 
 
 This is a college text-book. The volumes are written for use in 
 such institutions as give their undergraduates a reasonably good 
 mathematical training. It is intended for teachers who desire to 
 treat their subject as an exact science, and who are prepared to 
 supplement the brief subject-matter of the text by demonstrations, 
 illustrations, and discussions from the fund of their own knowl- 
 edge. A modern scientific work. Knowledge of calculus is nec- 
 essary for intelligent reading. An excellent book of reference for 
 teachers. 
 
 A Text-Book of Physics. 
 
 Authors, J. H. Poynting and J. J. Thompson. Published 
 by Charles Griffin & Co., London. Size, 6 in. x 9 in. Pages, 
 about 350 in each volume. Date, 1906. Many illustrations. 
 Vol. I, Properties of Matter, $4.25. Vol. II, Sound, $2.75. 
 Vol. Ill, Heat, $2.90. Vol. IV, Magnetism and Electricity. 
 Vol. V, Light. 
 
 This is a valuable and very comprehensive treatise, designed to 
 be a complete text-book for students who lay stress on the experi- 
 mental part of Physics. The mathematics used is mostly elemen- 
 tary. The book is written in the English style. The descriptions 
 are all minutely detailed, and cover the whole field of physics. 
 Vols. IV and V will soon be issued. 
 
 A Text-Book of Physics. 
 
 Author, W. Watson. Published by Longmans, Green & Co. 
 Size, 5 1-2 in. x 7 1-2 in. Pages, 896. Date, 1899. Price, 
 $2.90. 
 
 This is one of the best general reference treatises on Physics. 
 It assumes some knowledge of the elements of physics, also ele- 
 mentary algebra, geometry and trigonometry in certain portions. 
 There is no attempt to describe experiments illustrative of the 
 various phenomena, but the discussion of phenomena and the prin- 
 ciples involved is very complete. Much of it is valuable for high 
 school pupils, a part of it is too difficult. It is intended to be a 
 college or scientific school text-book. The 564 figures are almost 
 entirely diagrammatic. 
 
8 General Treatises 
 
 The Mew Knowledge. 
 
 Author, Prof. Robert K. Duncan, of Washington and Jef- 
 ferson College. Publisher, A. S. Barnes & Co., 11 East 24th 
 Street, New York; 101 Tremont Street, Boston. Size, 
 5 1-2 in. x 8 1-4 in. Pages, 263. Date, 1905. Price, $2.00. 
 
 This is an excellent resume of the modern theories regarding 
 the composition of matter and the conservation of energy. In clear 
 simple language it states the newest ideas evolved from the study 
 of radio-activity. It is interesting reading for the student and the 
 teacher because of its comprehensiveness and its plain presentation 
 of the subject It is well worth a place in every physical and 
 chemical laboratory. 
 
 Matter, Ether, and Motion. 
 
 By Prof. A. E. Dolbear. Published by Lothrop, Lee & 
 Shepard Co. Size, 5 1-4 in. x 7 3-4 in. Pages, 334. Re- 
 vised edition. Price, $2.00. 
 
 The author discusses the properties of matter and the character- 
 istics of the ether with their possible relation to each other. The 
 chapters on the origin and nature of heat, ether waves and elec- 
 tricity are written in a manner which makes clear recent views. 
 It is likely to secure and hold the interest of any reader, and to be 
 stimulating and suggestive. The subject is treated entirely from 
 the standpoint of the molecular and ether theories. 
 Matter, Energy, Force, and Work. 
 
 Author, S. W. Holman. Published by the Macmillan Co. 
 
 Size, 5 in. x 7 1-2 in. Pages, 257. Date, 1898. Price, $2.50. 
 
 A discussion of "fundamental physical concepts." It is intended 
 for the teacher or advanced student. It is particularly valuable 
 for its statements of various theories of matter and energy. The 
 treatment is historical as well as critical, and the reader can feel 
 that in some measure he has covered the entire ground. Le Sage's 
 Theory of Gravitation and the Vortex Atom Theory is discussed 
 in an especially interesting manner. Portions of the books would 
 be read with pleasure and profit by high school pupils scientifically 
 inclined. 
 Wares and Ripples in Water, Air, and Ether. 
 
 Author, J. A. Fleming, F. R. S. Published by D. Van Nos- 
 
 trand Company. Size, 7 1-4 in. x 5 in. Pages, 299. Date, 
 
 1905. Price, $2.00. 
 
 This contains a course of Christmas Lectures given before the 
 Royal Institution, London. The discussion is remarkably clear, 
 simple, and free from technicalities. It presents many experiments 
 that are both interesting and simple and is a storehouse of facts 
 concerning waves of all kinds. It will perhaps prove more help- 
 ful to the teacher than to the class; and yet it is just the book to 
 which to send boys and girls for the investigation of specific topics. 
 The best thing in the book is the brief, simple, and thoroughly 
 intelligent account of the nature and production of electric waves.

 tific Use of the Imagination," "On Radiation," "Radiant Heat," also 
 "About Common Water," "Atoms, Molecules and Ether Waves," 
 "Life in the Alps," and many other topics not directly connected 
 with our instruction in Physics. Though published several years 
 ago they are well worth reading and will always be so. They are 
 valuable for both pupil and teacher. The author's name is suffi- 
 cient guaranty that the essays are accurate and interesting.

 International Catalogue of Scientific Literature. 
 
 Publisher, Harrison & Sons, 45 St. Martin's Lane, London. 
 
 Those who can have access to some large library, as the Boston 
 Public Library, will find this a very valuable guide to Scientific 
 Literature. It devotes to Physics alone, each year (beginning 1902) 
 one complete volume of 300 to 400 pages in giving a full list of 
 books and periodical articles issued during the previous year. 
 This takes up articles in all departments of Physics as issued in 
 various languages. It is well classified by authors and by sub- 
 jects, and is of great value to a teacher who is making a thorough 
 study of some branch of Physics. 
 
Mechanics 1 1 
 
 MECHANICS. 
 
 Mechanics, (Cambridge Physical Series). 
 
 , Author, John Cox, F. R. S. C. Publisher, Cambridge Uni- 
 versity Press. Size, 5 1-2 in. x 9 in. Pages, 332. Date, 
 1904. Price, $2.75. 
 
 The author attempts to develop the principles in historic order, 
 starting from real problems, and showing how the great investi- 
 gators proceeded. He interests the student in the personality of 
 the great physicists. The mathematics is reserved until the close 
 of the course. The subject is divided into four books: I, The Win- 
 ning of the Principles; II, Matter and Statement of Principles; III, 
 Application to Problems; IV, Elements of Rigid Mechanics. 
 
 Elementary Experimental Mechanics. 
 
 Author, A. Wilmer Duff, D. Sc., of Worcester Polytechnic 
 Institute. Publisher, The Macmillan Co. Size, 7 1-2 in. x 
 
 5 in. Pages, 267. Date, 1905. Price, $1.50. 
 
 An excellent work. Theory and practice are combined as closely 
 as possible. Grasp of principles emphasized rather than skill in 
 measurements. The book contains many illustrations, diagrams, 
 problems and reference tables. The apparatus is largely that which 
 is made by the' International Instrument Company of Cambridge. 
 Very useful for lecture work in high schools. Theoretical state- 
 ments are concise. 
 
 Principles of Mechanics. 
 
 Author, T. M. Goodeve. Published by Longmans, Green

 Price, $2.00. 
 
 A general treatise on mechanics with applications to common 
 forms of machinery. The treatment is rather mathematical, but 
 the application of principles to mechanics is very clear. It would 
 be mainly useful to the teacher. 253 wood cuts. The author makes 
 continual reference to the practice and experience of mechanics, 
 and emphasizes the relation of the theory of heat to mechanics. 
 An appendix contains many problems.

 Cuts, 259. Price, $2.00. 
 
 This is almost entirely theoretical. Its chief point of value is 
 its discussion of the work of eminent investigators in the early his- 
 tory of the science. Special attention is given to Galileo, Newton 
 and Huygens, and many other early investigators, showing the 
 origin of many modern theories. It contains interesting cuts of 
 old prints. 
 
 Mechanics for Engineers.

 A first course in the principles of Mechanics for engineering stu- 
 dents. The gravitation system of units is used as prevailing among 
 engineers. Calculus not used. Energy, work, power, and graphical 
 statics given prominence. A valuable supplementary book for 
 teachers and advanced secondary pupils. Too difficult for ordinary 
 classes. 
 
 Mechanics, Molecular Physics and Heat. 
 
 Author, R. A. Millikan, Ph.D., Chicago. Published by Ginn

 Price, $1.50. 
 
 This is a combined text-book, laboratory and problem book, cov- 
 ering one-third the course in Physics, and adapted to the first 
 course in Physics for college pupils who have had a year of sec- 
 ondary school physics and some trigonometry. Of value to sec- 
 ondary teachers in showing the trend of modern study of Physics in 
 our most progressive colleges. Old ideas eliminated, modern inves- 
 tigation methods emphasized.

 Longmans, Green & Co. Size, 7 1-2 in. x 5 in. Pages, 284. 
 Date, 1901. Price, 90 cents. 
 
 Although elementary, this work is designed for a second year's 
 course in the field of Physics. It describes experiments very 
 minutely and contains many excellent suggestions for a class 
 in Physics which has completed a preliminary year's course. While 
 mostly experimental, it contains much theory interwoven with 
 experiment. The treatment of Heat is quite full. 
 
 Theory of Heat.

 internal forces, Heat engines, Latent Heat, Radiation, Convection, 
 Conduction, Elasticity and Vicosity, together with various theoret- 
 ical discussions. 
 
 The Theory of Heat. 
 
 Author, Thomas Preston. Published by The Macmillan 
 Co. Size, 7 in. x 9 in. Pages, 719. Date, revised edition, 
 1904. Price, $6.00. 
 
 This is a comprehensive and authoritative treatment of the sub- 
 ject, and forms, with its companion volume, Preston's Theory of 
 Light, an excellent treatment of Heat and Light. The subject is 
 developed in its historical order, the classical experiments being 
 described in detail. The Kinetic Theory of Gases is taken up only 
 so far as to meet the immediate requirements of the author. In 
 the chapters on Thermodynamics calculus is used freely and in 
 other chapters occasionally. There are 190 cuts and frequent tables 
 of constants. It is a standard book of reference. 
 
14 Heat 
 
 An Elementary Treatise on Heat.

 text-book. 
 
 Heat. 
 
 Author, P. G. Tait. Published by The Macmillan Co. Size, 
 5 in. x 7 1-4 in. Pages, 372. Date, 1892. Price, $2.00. 
 
 This elementary work is not easy reading, owing more to the 
 author's style than to the mathematical treatment of the subject. 
 Calculus appears occasionally. The contents include: 1. Nature of 
 Heat. 2. Effects of Heat. 3. Measurement of Heat and Temperature. 
 4. Sources of Heat. 5. Transference of Heat. 6. Transformation of 
 Heat Experimental illustration of the discussion is sparingly used. 
 
 Heat, a Mode of Motion. 
 
 Author, John Tyndall. Published by D. Appleton & Co. 
 
 Size, 5 1-2 in. x 8 in. Pages, 591. Date, 6th edition, 1898. 
 
 Price, $2.50. 
 
 This well known book, which dwells upon the historical devel- 
 opment of the subject, treats of heat as it would be taken up in a 
 series of experimental lectures. The molecular constitution of mat- 
 ter and the conservation of energy appear to be the central 
 thoughts around which the various phenomena are grouped. It is 
 a valuable book of reference. 
 
 Heat as a Form of Energy. 
 
 Author, Robert H. Thurston. Published by Houghton.

 $2.00. 
 
 This book deduces the laws of optics and consequences of the 
 undulatory theory of light, but at the same time no very decided 
 line is drawn between physical and geometrical optics. Contents: 
 Wave motions and their propagation, Reflection and Refraction, 
 Interference, Diffraction, Spectra, Double Refraction and Polarized 
 Light, Electro-Optics, Velocity of Light. A good reference book for

 The Macmillan Co. Size, 6 in. x 9 in. Pages, 586. Date, 
 3d Edition, 1901. Price, $5.00. 
 
 The author endeavors to give an account of the most important 
 optical researches from the earliest times up to the present. The 
 text contains, in addition to the physical theory, a detailed account 
 of the most important experiments and physical measurements, 
 such as the determination of the velocity of light, wave lengths, 
 refractive indices, etc. Some of Newton's fundamental experi- 
 ments on refrangibility of light and colored rings are taken from 
 the original accounts, the author in this way endeavoring to direct 
 attention to Newton's work, and to show that in this department of 
 scientific research as in some others he stands almost without a 
 rival. There are 251 excellent cuts. The book is one of the best 
 reference books on the subject that is available.

 mans, Green & Co., agt.). Size, 5 1-2 in. x 8 3-4 in. Pages, 
 340. Date, 1904. Price, $4.00. 
 
 This is an exposition of the Electro-magnetic theory of light, and 
 an attempt to reduce to a mechanical basis the equations and prin- 
 ciples now accepted as the electro-magnetic theory. Part one, in 
 which the mathematics is more simple, would be of much interest 
 to the teacher who has a good working knowledge of trigonometry. 
 It is too mathematical for high school pupils. 
 
 Practical Exercises in Light. 
 
 Author, Reginald S. Clay, D. Sc., London. Published by 
 The Macmillan Co. Size, 5 in. x 7 in. Pages, 183. Date, 
 1902. Price, 60 cents. 
 
 Designed to be a laboratory course for scientific schools, with 
 descriptive notes. Since the apparatus is mostly simple and the 
 mathematics elementary, it is nearly all within the range of high 
 school pupils. Well suited to advanced classes in high school 
 Physics.

 Price, $2.00. 
 
 A series of most interesting and popular lectures. Each lecture 
 is followed by an appendix discussing the theory suggested by the 
 lecture. Geometrical optics, anomalous refraction, the elastic 
 solid theory of light, and the electro-magnetic theory of light are 
 here discussed. It contains a most admirable account of the forma- 
 tion of the spectrum and the phenomena connected with it. Special 
 attention is paid to effects produced at the ultra-violet and infra- 
 red ends. Phenomena of polarization and fluorescence are also 
 explained. The book is one of great value to pupils for collateral 
 reading, and is no less valuable to teachers. The style is fascinat- 
 ing and it contains no mathematics except in the appendices. It is 
 thoroughly up to date and is well illustrated. It presents many 
 suggestive experiments for the lecture room.

 An experimental course in Physical Optics in which projection of 
 the phenomena upon the screen is made much of. The aim of the 
 hook is "to give such a clear conceptual grasp of the chief facts in 
 Physical Optics as may make text-books real," by means of "some- 
 thing like a complete course of actual experiments on the physical 
 realities which underlie the phenomena of Light and Color." The 
 author has chapters on (1) The Lantern and accessory apparatus, 
 (2) Reflection, (3) Refraction, (4) Spectra, (5) Undulatory Theory 
 of Light, (6) Color, (7) Spectrum Analysis, (8) Phosphorescence and 
 Fluorescence, (9) Interference, (10) Double Refraction and Polari- 
 zation. (11-15) A Complete Discussion of Polarization. There are 
 nine full page colored plates and 207 excellent cuts and diagrams. 
 The book is non-mathematical in its treatment of the subject and 
 is a valuable reference book for use of pupil or teacher.

 Co. (International Science Series.) Size, 7 1-2 in. x 5 in. 
 Pages, 309. Date, 1896. Price, $1.50. 
 
 The author attempts to answer as far as possible in a popular 
 way the question asked in the title. He endeavors to show that 
 electricity can be traced back to the energy of the sun hence its 
 relation to heat and light. The book discusses continually the doc- 
 trine of conservation of energy with reference to all elec- 
 trical phenomena, and makes clear the transformation of these 
 varieties of energy. The electro-magnetic theory of light is ex- 
 plained. The book is well illustrated by means of diagrams; it is 
 suggestive to a teacher and could be placed in the hands of some 
 pupils with profit.

 University. Published by American Book Company. Size, 
 8vo., 5 1-2 in. x 8 1-2 in. Pages, 544. Date, 1898. Price, 
 $1.80. 
 
 This book contains 91 experiments, well distributed among the 
 divisions of general physics, chapters on Laboratory Equipment, 
 Laboratory Receipts and Methods and Galvonometers, 30 tables of 
 constants, tables of logarithms, natural sines, cosines and tangents. 
 Only quantitative experiments are described. Each experiment is 
 treated in even parts: (1) Object of the experiment in a single para- 
 graph; (2) general theory, a brief statement of the theory and the 
 physical laws involved; (3) sources of error discussed and the most 
 important difficulties with the necessary precautions are pointed 
 out; (4) a list of apparatus to be used, with a brief description; (5) 
 manipulation, a full statement of details with explicit directions; 
 (6) illustrations, the result of actual experiments performed in the 
 manner described, and intended to serve as a guide in making 
 reports and to show practically how accurate the experimental 
 methods are; (7) questions and problems. The work outlined in 
 this book is intended for college students, but the methods of 
 presentation and many of the experiments themselves make it a 
 very suggestive and valuable book of reference for the teacher in 
 planning his laboratory work.

 performing a large number of experiments illustrating physical 
 phenomena, in such a way that they may be projected upon the 
 screen. By this means pupils in large classes can be instructed 
 and interested by many experiments which would otherwise be 
 invisible to all except a few nearest the lecture table.
