palm, the almond and the sugar-cane, the mulberry and the cotton-tree, the citron 
and the olive, all growing side by side. Here was perpetual spring." 
Recently tourists are turning their attention in this direction more than 
formerly, several citizens of this region, even, having visited its classic shores 
and medieval cities within the past few years. 
The author of this work writes very pleasantly and instructively of Barcelona, 
which is so old that the local historians claim that Hercules founded it 400 years 
before Romulus was born ; of Montserrat, one of the many and perhaps the most 
celebrated of the sacred shrines of Spain ; of Saragossa, the capital of Arragon, 
named after Caesar Augustus ; of Madrid, with its treacherous climate, its attrac- 
tive armory, museum and picture galleries, of the Escorial, a sublime and costly 
monument of folly erected to the memory of Charles V ; of Toledo, once the 
capital of the Goths, then of the Moors and finally of the Christians, each of whom 
in turn devoted it to the priests and kings ; of La Mancha, better known as the 
*' stamping-ground " of Don Quixote and his doughty squire, Sancho Panza, than 
for anything else. Cadiz, Gibraltar, Tangier, Morocco, Malaga, and Burgos, 
each receive a description, and the book closes with the Pyrenees, with their 
lofty snow covered peaks, remaining both as to cultivation and the habits and 
customs of the people, in the same primitive state as centuries ago. 
The reader will be well repaid for the time consumed in reading this book. 
Manual of Assaying Gold, Silver, Copper, and Lead Ores : By Walter 
Lee Brown, B. Sc, with illustrations; i2mo., pp. 318. Jansen, McClurg 
& Co., Chicago, 1883. $1.75. 
This work, though prepared especially as a guide to students and persons 
having no previous technical knowledge of assaying, will be found very useful to 
all who have occasion to refer to a thoroughly practical hand-book. It is clearly 
and plainly written, with all necessary details, descriptions of apparatus, reagents 
and processes for the unpiracticed operator, while the appendix contains instruc- 
tions for special methods, lists of gold, silver, copper, and lead-bearing minerals, 
lists of books applicable to the subject, etc. 
As an evidence of the practical method and form of its arrangement we select 
from the table of contents a few titles of chapters and sections, premising that 
there are sixty-nine illustrations of the various implements and tools used in assay- 
ing. Eighty-one pages are devoted to describing apparatus, such as scales and 
balances, furnaces and furnace tools, glass and porcelain implements, and mis- 
cellaneous apparatus ; twenty-seven pages to reagents, such as wet and dry re- 
agents for assaying and reagents for^analysis : eight pages to preliminary work, 
testing reagents, etc.: forty-two pages to the assaying of gold and silver ores, with 
their occurrence, preparation of the sample, assay by the scorification process and 
by the crucible process : four pages to the assay of copper ores by the method for 
mative copper, the method for oxides and carbonates of copper free from sul- 
iphur, and the method for the sulphides of copper with antimony, arsenic, etc. ,
