Zovencedo and Mure (Vicenza), Soligo (Treviso), and on the Taclia- 
mento (Udine), succeed. Then come the lignites of the Apennine 
regions, especially on the Rubicone (Forli), of Agnana (Calabria), 
Cadibona and Sarzana (Genoa), Ghivizzano (Lucca), Upper Arno 
Valley, and others in the districts of Florence, Pisa, Grosseto, and 
Sienna; also the lignites of Sardinia and Sicily. In Italy 281 com- 
munes of 46 Provinces yield lignite. 
The frequent and important peat-beds of the Alpine and Apennine 
regions are noticed in much detail. Peat occurs in 198 communes 
of 29 Provinces in the Kingdom of Italy. 
To geologists and others interested in Italy and its mineral 
products, some other works by Signor Gulielmo Jervis are of great 
utility,—namely, his ‘‘ Subterranean Treasures of Italy” (‘I Tesori 
sotterranei dell’ Italia’’), and his “Guide to the Mineral Waters of 
Italy ” (‘Guida alle Acque Minerali,” etc.). 
They have been complimented with “ Honorable Mention ” and a 
prize in Paris and Rome. The author’s English work “On the 
Mineral Resources of Central Italy,” treating especially of the mines 
and marbles, is almost out of print now. Signor Jervis is careful 
in statement of facts, and bold in his expressed views. He warns 
his readers of the fallacy of referring the increase of temperature in 
springs to central heat. He does not accept the volcanic origin of 
the boracic-acid lagoons of Central Italy. He refers the “ gabbro 
rosso” of that region to a sedimentary origin; and separates it from 
the “‘gabbro” of the Germans, or euphotide. The non-diallagic 
serpentine he regards as having been derived in many cases from 
a metamorphosis of the diallagic variety. The gold of Northern 
Italy, found in the beds of certain rivers, he traces to its source in 
the pre-Paleozoic rocks of the Alps, where it occurs in minute 
quantities mechanically mixed with pyrites. T. B.J:

The above measures are cupriferous and rest on limestone with 
Zechstein fossils. Associated with the remains of Saurians and 
Labyrinthodonts are Calamites, Lepidodendron, Aroides crassispatha, 
Conifers, and a Unio. The specimen noticed in this paper is appa- 
rently the dentary part of the left mandibular ramus, with the 
crowns of a canine, an fhcisor, and ten of the molars. The author 
describes the characteristics of these and the mode of implantation 
in the jaw, which accords with that described by Prof. Owen in 
Titanosuchus ferox. The characters of this specimen resemble those
