193 Bibliography. 



works therefore now occupy ground entirely distinct. The Elements 

 has grown from one volume, in which the first edition was published, 

 into two, each equal to the former ; while the Principles have been 

 brought down to the latest dates by the addition of much new matter, 

 which has appeared since 1837, and some opinions formerly advocated 

 are reclaimed as having been superseded by the advance of " a philo- 

 sophy which never rests — its law is progress : a point which yesterday 

 was invisible is its goal to-day, and will be its starting point to-morrow." 



11. Notes on the use of Anthracite in the Manufacture of Iron, with 

 some remarks on its evaporating power ; by Walter R. Johnson, 

 A. M., &c. Boston, 1841. 12mo. pp. 156. C. C. Little & Jas. Brown. 



Every gleam of light on this important subject is most welcome to 

 all who are interested in the prosperity and permanent advancement of 

 this country. That which three or four years since was deemed im- 

 possible, is now the subject of daily practice ; and the day is not far 

 distant when the anthracite iron of Pennsylvania will supersede to a 

 gi'eat extent the importation of the foreign article, by substituting at 

 home a cheaper and better. 



As the amount of experience in this new branch of metallurgic art 

 is not great, there was no call for a great book. Prof. Johnson has 

 therefore brought into a compact form all the information which could 

 be collected on the subject, and tabulated the results of those blast fur- 

 naces in Pennsylvania which are driven by anthracite, under all the 

 heads most valuable to the practical man. Our limits do not admit 

 any extension of this notice, or we would give an analysis of the con- 

 tents of the volume, which we are now obliged to defer to another op- 

 portunity, 



12. American Almanac and Repository of Useful Knowledge for the 

 year 1842. Vol. XIII. Second Series, Vol. ^. Boston : D. H. Wil- 

 liams. — This volume contains the usual amount of interesting statistical 

 matter, with the results of the new census, statistics of education, &c. 

 The astronomical portion has changed hands this year, from Mr. H. 

 T. Paine, who has so long and ably conducted it, to Prof. Peirce, of 

 Harvard University. The high reputation of Prof, Peirce will insure 

 every attention and improvement. 



13. Prof ParFs Pantology. — In our last, we inadvertently missta- 

 ted Prof. Park's classification of human knowledge, being misled by an 

 error in the divisions of his tree of knowledge. We now give the order 

 correctly.
