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, — : vs 
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are reclaimed as having been superseded by the advance of ‘a philo- 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 a's to-morrow.” 
11. Notes on the use of Anthracite in the cen of Tron, with 
some remarks on its evaporating power; by ~ rer R. Jownson, 
A. M., &e. Boston, 1841. 12mo. pp. 156. C.C. inte we Sa 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 
great 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 fora 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. ee

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