360 Notices of Books. [July, 
be compiled, and Messrs. Collins have done well to include a 
Manual of Metallurgy in their ‘‘ Advanced Science Series.” 
Mr. Greenwood has written the work with the view of meeting 
the requirements of the Kensington syllabus, and has succeeded 
in producing an extremely serviceable little Manual. Of course 
there is no room in so elementary a work for any original treat- 
ment of the subject, but the writer gives a succinct analysis of 
what others have written, and has evidently profited by his 
training under one of the best metallurgists in this country. 
After defining the terms peculiar to Metallurgy, Mr. Greenwood 
devotes a chapter to Fuel, and then passes to the study of Iron 
and Steel, which forms, indeed, the bulk of the book. The 
minor metals—tin, antimony, arsenic, bismuth, and platinum— 
are then briefly disposed of ; but we fail to see what principles 
of classification have induced the writer to thus bring these 
rarer metals into juxtaposition with iron. The modern chemical 
notation, nomenclature, and atomic weights are employed, and 
the information generally is brought up to date. But although 
thus satisfactory as a whole, it would, of course, be easy enough 
to find fault with certain parts of the work. It is to be regretted 
that wherever German expressions are employed they are always 
bungled. Thus the writer cites, in his preface, ‘‘ Bruno Kerl’s 
Handbuch der Metallurgischen” (sic) ; again, we are surprised 
to find the common word Sfiegeleisen incorrectly spelt wherever 
it occurs. But trivial typographical errors of this kind, although 
annoying to an observant reader, do not, after all, detract much 
from the merits of the Manual. Indeed we hope that Mr. Green- 
wood will be as successful in his second volume—a volume 
which will deal with the remaining metals—as he has been, on 
the whole, in the present instalment of his work. 
The Best Mining Machinery; an Essay. By RatpH Go.ps- 
wortHy. Reprinted, with Alterations and Additions, from 
the Royal Cornwall Polytechnic Society’s 41st Annual 
Report, 1873. 
ORIGINALLY printed in the ‘‘ Mining Journal,” and afterwards in the 
‘‘Report of the Cornwall Polytechnic Society,” this Essay is already 
known to a large number of those who are interested in mining. 
Nevertheless it is of so useful a character as to fully deserve a 
separate issue. Mr. Goldsworthy brings a good deal of practical 
knowledge to bear upon his subject, and gives the reader the 
benefit of a wide experience. It is a thoughtful and suggestive 
Essay, which will be read with interest by all who are connected 
with metalliferous mines.
