of Post-pliocene trachyte of the Solfatara; triumphal arch of 
Augustus at Susa, the cathedral of Milan, and the front of the 
Palazzo Madama, Turin, of white Pre-paleozoic marble; and the 
Railway-station at Turin, of Pre-palzozoic syenite and gneiss. The 
sources of the material of these and of the numerous other pictured 
buildings, statues, ete., are carefully given. Besides those mentioned 
above there are views and sketches of the mountainous districts that 
yield marble, of some quarries, and the rough modes of hauling the 
blocks by means of cruelly used bullock-teams; also of Vesuvius, 
Lipari, Pompeii, cement-factories, palaces, churches, bridges, statues, 
catacombs, cave-dwellings of Posilippo, ancient amphitheatres and 
temples (Roman and Greek), and of the enigmatical pre-historic 
buildings (Nuraghi) of Sardinia. 
At page xv is a list of sixty-five authors who have described the 
economic stones and other such Italian materials used in construction, 
decoration, inlaying, ete. 
The Preface and an Introduction, explaining the author’s plan 
and intention, with a brief exposition of the bearing of Geology on 
the subject of his work, follow appropriately to page XXXII. 
At p. xxx a list of the economic rocks of Italy (eighty-nine) 
described in this volume is given. ‘The effects of atmospheric action 
on the different kinds of rock and stony materials are noted at pp. 
XXXIV-XXxv; and the relative composition and character of cements, 
mortar, and plaster, at p. XXXVI. 
Page 1 commences with a catalogue of the ancient and modern 
names of places, the economic geology of which is mentioned in the 
volume. At pages 2 and 8 is a provisional or tentative Table of the 
chief geological formations occurring in the Italian Alps, according 
to the writings of accredited geologists, with indications of the 
different economic materials found in or made from the several 
rocks. At pages 4 and 6 is a similar carefully-constructed Table of 
the rocks and strata of the Apennines and their associated volcanoes. 
A similar Table for Sicily is presented at pp. 6 and 7; and one for 
Sardinia at p. 8. A concise list of leading Fossils for each of the 
above-mentioned regions is given at pp. 9 and 10. Pages 11-13 
are occupied by a classified and alphabetical list of the Communes 
and Provinces mentioned in the Volume, with the respective numbers 
of the paragraphs concerned. At p. 32 is a list of fifty-five modern 
cities where Italian marbles, or ornamental and kuilding stones 
have been used. 
Not only is this volume full of matters of general interest to the 
educated reader, but it is a valuable repertory of useful information 
for provincial and communal administrations, for capitalists, technical 
colleges, and geologists. 
Two useful and carefully compiled Indexes complete the volume. 
1. An Alphabetical Index of the Communes in which the several 
economic materials described in the volume, and here arranged 
under their lithological headings, have been met with. 2. A simply 
Alphabetical Index of the Communes in which the said rocks have 
been found.
