and ten pages to the assays of lead ores by the nsethods for galena and by the- 
methods for oxides and carbonates. 
All of this is most carefully worked out and thoroughly detailed, so that 
apparently an ordinary assay may be made by an inexperienced hand after a very 
brief practice. 
The appendix contains explanations of and directions for assaying of the 
various minerals contained in an ore ; of ores containing free gold or free silver ; 
analysis of copper ores, amalgamation assay or laboratory mill-run ; pan-test for 
gold " panning "; chlorination assay for gold ores ; chlorination test for silver; 
assay of gold bullion and base bullion ; color tests, scorification, scorifier, cupel ; 
quahtative tests, carbonates, chlorides, sulphates, sulphides, tellurides, copper, 
iron, lead, silver; a brief scheme for silica, iron and manganese, and determina^ 
tion of moisture in an ore. 
To this is added a chapter giving lists of the principal gold minerals in the 
United States, and minerals likely to carry gold ; list of the principal silver min- 
erals found in the United States, and minerals likely to carry silver ; list of prin- 
cipal copper and lead-bearing minerals of the United States; list of useful books 
upon assaying, chemical technology, laboratory manipulation, mining law, etc. 
Section third comprises tables of values of gold and silver, tables of weights ;, 
equivalents of some English and French weights ; assay ton equivalents in gram- 
mes, Troy grains and Troy ounces. The work closes with a copious and well 
arranged index. 
We have been more particular than usual to give in detail the contents of 
this manual because we have been asked severa] times by friends and acquaint- 
ances engaged in prospecting and mining to recommend a simple and practical 
work suited to the circumstances and surroundings of such persons. This we 
can candidly do in regard to this book and at the same time assure them of a 
neat, tasteful, well printed volume at a low price. 
Italian Rambles: By James Jackson Jarves; i6mo., pp. 446. G. P. Putnam's 
Sons, New York, 1883. For sale by M. H. Dickinson; $1.25. 
In this study of the life and manners in the new and old Italy, the reader 
perceives the difference between the work of the hasty tourist who rushes across 
the country by rail and writes his observations from the guide-book, and that of 
the experienced traveler who has given months and perhaps years to a district, 
until he knows its byways as intimately as its highways. 
Mr. Jarves has spent many years in Italy, and these "Rambles" are the 
resultant. No one can read them without observing an unaccustomed tone of 
familiarity with the various topics treated, frequently wanting in the sketches of 
better known writers and travellers. Besides this, the style of the author is 
familiar, breezy and artistic, showing the scholar and the man of taste. The 
topics are mostly outside of the range of the ordinary observer, which renders, 
them still more attractive. Pescaglia, Serra in the Appenines, In Porsenna's-
