SCIENCE AND INDUSTRY. 
In arrangement, the new book differs markedly from the former work, which 
was. somewhat cumbersome in this respect. The division into parts has been 
discarded, and related subject-matter has been more closely co-ordinated than in 
the previous work, as may be seen from the following:—In chapter I. is given 
a rather comprehensive synopsis of the principles of mechanics of materials. 
Chapters II. and III. deal with machines and appliances for testing,. the 
technique of testing, and the utility of the various tests. Chapters IV. to VI. 
consider the characteristics, methods of identification, properties, and uses of 
the more important native woods, also causes of decay and means of preserya- 
tion. Chapter VII. treats of the important stones, their constitution, durability, 
and properties. Chapter VIII. covers the manufacture and testing of structural 
clay products, together with their mechanical properties and uses. Chapters IX. 
to XII. deal with the nature, manufacture, methods of testing, and properties 
of the hydraulic cements, the limes, and the plasters. Chapters XIII. to XY. 
describe fully methods. of making mortar, concrete, and concrete products; also 
the properties and uses of these materials. Chapter XVI. provides a brief 
summary concerning the utility of the principal metals, their ores, and the 
fundamental considerations governing their extraction. Chapters XVII. to XTX, 
treat of the reduction of iron from its ores, and the subsequent operations of 
purification and fabrication into final form. Chapters XX. and XXI. deal with 
the formation and structure of alloys in general, and the constitution of iron 
and steel. Chapters XXIT. to XXIV. are devoted to a discussion of the pro- 
perties and uses of wrought iron, steel, and alloy steels. Chapter XXV. takes 
up the manufacture, molding, constitution, and properties of cast iron and 
malleable cast iron, Chapter XXVI. treats of the production, properties, and 
uses of copper, zinc, aluminium, lead, tin, nickel, and their alloys. Chapters 
XXVII. to XXIX. cover the effects of temperature on metals, the causes and 
effects of fatigue, and the corrosion and protection of metals. 
Diagrams and charts are extensively used for the presentation of facts and 
laws. These and the omission, wherever possible, of cumbersome tables, con- 
siderably add to the value of the’ book. : :
