Reviews—Chevr. Jervis’s Treasures of Italy. 175 
geology of the district and its component rocks or strata are briefly 
noticed in smaller type. There are, further, short historical sketches 
of the uses to which the materials have been applied during the 
course of thirty centuries, by the Htruscans and Romans, and by the 
Greek, Evyptian, Phoenician, and Pelasgian colonists of Southern 
Italy, and their several descendants down to our own times. Hence 
we are here shown of what stones a very considerable number 
of classic temples and other edifices, monuments, tombs, votive 
altars, and statues were constructed. Descriptive notices also 
are given of catacombs, aqueducts, roads. bridges, and other public 
works of the ancients and moderns,—all from a geological stand- 
point. Thus the great antiquities of Italy have been brought forward 
in a novel and highly intelligent and interesting manner, far beyond 
the reach of existing Guide-book literature; and both tourists and 
others can, like true students, not merely seek to collect new facts, 
but study known facts better. 
The localities of rocks of economic value (excepting sands and 
clays) are indicated, that are within accessible distances from towns, 
roads, railways, and ports. Some of the most interesting places 
referred to as containing objects worthy of notice by the lithologist 
and geologist, as well as the antiquary, are—Volterra, Cortona, 
Carrara, Fivizzano, Lerravezza, Rome, Tivoli, Naples, Pozzuoli, 
Syracuse, and Sardinia. 
Our author seems to us to have succeeded in carrying out Pliny’s 
object, when he was striving (as he said 1800 years ago) to treat 
old subjects in a fresh readable light. The old Roman’s opinion is 
given as an epigraph to the Introduction at page xx1, and may be 
read as follows :—“ It is difficult to give novelty to ancient things 
and authority to new; brightness to obsolete and light to obscure 
things; pleasure to the fastidious and faith to the doubting; a 
naturalness indeed to everything and everything to its own nature.” 
This volume mainly consists of three parts. 1. The Alps 
(pp. 82-164, with 19 illustrations) ; 2. The Apennines and the 
volcanoes, both active and extinct (pp. 165-414, with 80 illustra- 
tions); 38. The Islands of Sardinia and Sicily (pp. 417-482, with 
9 illustrations). These regions are treated in detail according to 
their hydrographic basins, provinces, and communes, which yield 
building-stone, marble, ete. 
A list of the Illustrations is given at pp. x1—xrv, with indications 
of the materials used in the several buildings shown,—as, for 
instance, part of a Pelasgian wall at Croton (Cortona), made of 
great blocks of Eocene sandstone (pietra serena) ; part of Etruscan 
funereal monument, in Miocene alabaster; Etruscan mortuary tomb, 
of Quaternary travertine; the “cloaca maxima” at Rome, con- 
structed of Post-phocene volcanic tuff, of travertine from Tivoli, 
and of Post-pliocene peperino; Roman amphitheatre at Verona, of 
compact Jurassic marble; the Pantheon at Rome, with granite 
columns; the baker’s house at Pompeii, with mill-stones of late 
Tertiary leucitic lava; pavement of the “ Via Appia,” of Post- 
pliocene basalt; pavement of the Roman mole of Puteoli (Pozzuoli),
