THE POPULAR SCIENCE MONTHLY. 



at which Dr. Todhunter left it. The present 

 volume covers the period from Saint-Venant 

 to Lord Kelvin. It carries the analysis of 

 individual memoirs completely to the year 

 1860, but after that point the editor has 

 found it practicable to deal with the work of 

 certain elasticians only. These are the two 

 just named, with Boussinesq, Rankine, F. 

 Neumann, Kirchhofif, and Clebsch. Although 

 the part since 1860 is only the framework 

 of what Prof. Pearson hoped to make it, the 

 work is a monumental one. The number of 

 the memoirs included in the thirteen hun- 

 dred pages of the second volume by no means 

 measures the work expended ujjon this part 

 of the history. The study and analysis of 

 many other memoirs were involved in the 

 task. A systematic index, carefully prepared 

 by Pi-of. Pearson, is appended. 



We have received Part I (Kinematics) 

 and Part II (Dynamics and Statics) of An 

 Eltmenta)-y Treatise on TTieoretical Mechanics, 

 by Prof. Alexander Ziwei, of the University 

 of Michigan (Macmillan, $2.25 a volume). 

 The work owes its existence mainly to the 

 diiBculty of finding a good modern text-book 

 suited to the requirements of the American 

 student. While it is intended first of all as 

 an introduction to the science of theoretical 

 mechanics, the author has aimed to make it 

 serve as a preparation for the applications 

 in engineering practice, and to bring out the 

 utility of the purely mathematical training. 

 To keep the whole work within reasonable 

 bounds, the more advanced parts of the sub- 

 ject had to be strictly excluded. A third 

 part (Kinetics) will complete the treatise. 



T/ie Book of (he Fair, published by the 

 Bancroft Company, Chicago and San Fran- 

 cisco, is intended to reproduce and preserve, 

 by engraving and letterpress, all the charac- 

 teristic features of the recent exposition at 

 Chicago. The publishers claim that it is the 

 only work attempting to reproduce the expo- 

 sition in this way entire. " It confines it- 

 self," they say, " neither to art alone on the 

 one side nor to dry statistics on the other, 

 but aims to present hi attractive and accu- 

 rate form the whole realm of art, industry, 

 science, and learning, as here exhibited by 

 the nations, so far as can be done within 

 reasonable limits." The work will consist 

 of one thousand pages of twelve by sixteen 

 inches, will be issued in twenty-five parts of 



forty pages each, at the price of a dollar a 

 part, and will contain more than a thousand 

 illustrations, many of them full page. 



In ./. F. Mulholland' s revision of Dr. 

 Arnold's First and Second Latin Book and 

 Practical Grammar the labors of the editor 

 have been directed, first, to the removal of 

 all errors ; second, to a change of excep- 

 tional Latin expressions, which are declared 

 out of place in an elementary work ; third, 

 to simplicity of design, so that subjects 

 should not be prematurely thrust upon the 

 attention of the pupils ; and, fourth, to a 

 more consistent arrangement of the parts of 

 the Second Book. In the revision of Ar- 

 nold's Practical Introduction to Latin Prose 

 Composition, by the same editor, the matter 

 on the Sequence of Tenses, hitherto scattered 

 throughout the work, has, by means of refer- 

 ences, been unified, and that on Conditional 

 Propositions has, by the removal of much ver- 

 biage and some errors, been arranged so as to 

 be comprehensible to the ordinary student. 

 Also, whereas in the old book reference was 

 merely made to certain works on Synonyms, 

 in this edition, the works quoted not being 

 commonly in the hands of pupils, the proper 

 word is given. (Both of these books are 

 published by the American Book Company.

The Inductive Greek Primer of Drs. W. 

 R. Harper and C F. Castle is designed for a 

 beginner's Greek book and to meet the wants 

 of younger pupils as well as of those for 

 whom the Method is adapted. It differs 

 from the Method in that the lessons are 

 shorter ; the notes are more copious and 

 elementary ; the exercises are simple ; the 

 pupil's knowledge of Latin grammar is 

 drawn upon to illustrate and facilitate his 

 knowledge of Greek grammar ; the pupil is 

 taught to read Greek in the order of the 

 original ; the first occurrence of words is 

 specially indicated in both the text and the 

 vocabulary. The volume articulates with 

 the Greek Prose Composition of the same 

 authors. (American Book Company. Price, 

 $1.25.) 



In a book entitled The Gospel of Paul, 

 the author, Charles Carroll Everett, Profess- 

 or of Philosophy in Harvard Divinity School, 

 presents an interpretation of Paul's doctrine 

 of the atonement which he believes to be 

 new ; not a theory of his own " of a possi-
