the subjects of the illustrations, many of which, being facsimiles of the 
pencil memoranda made on the spot in the Note-book , are, as a matter of 
course, rough enough. Sketchy as the work is, however, the geologist will 
find many interesting details in it, and we think it is a pity that Mr. Lee, 
instead of arranging his materials in the order of date, did not adopt some 
sort of rough classification, such as would have served to guide those con- 
sulting his Notes more directly to the matters of which they may be in 
search. 
TIN. * 
T IN is one of those metals in which an Englishman may naturally take 
great interest. For many years it was supposed that the tin which 
furnished ancient nations with the means of making bronze was exclusively 
derived from the south-western corner of Britain ; and although this source 
of national vanity has been long dried up, there is no doubt that a very large 
proportion of the tin used in the world until quite recently was obtained 
from the Cornish mines. Nowadays, indeed, the development of tin-mining 
in other countries, and especially in the far east, where labour is cheap and 
the stanniferous deposits are still comparatively untouched, has thrown the 
old Cornish industry into the background, and it will probably be many 
years before the British stannaries can attain anything like their former 
prosperity. 
Nevertheless the production of tin, although it may be regarded as one 
of the minor metallurgical industries when compared with that of iron, 
copper, or lead, is of great importance, as the metal is applied to many pur- 
poses in which it would be hard to find a substitute for it. Those who take 
an interest in mining matters will therefore owe a debt of gratitude to Dr. E. 
Beyer, a distinguished Austrian geologist, who has devoted a great amount 
of labour to the investigation of the occurrence and working of tin ores in 
various parts of the world, and now publishes the results of his researches in 
a small octavo volume. 
As will be seen from the title of his book, he views his subject from all sides, 
except that of the actual smelting, although some particulars of the results of 
this operation are also given. He commences with some Bohemian and German 
localities, — Zinnwald, Altenburg, Graupen (where tin was mined as early 
as the year 1200), and Schlackenwald, then deals with Cornwall and some 
very limited occurrences of tin in the Iberian peninsula, France, Italy, 
and Finland, and finally describes the stanniferous regions of Malacca, 
Banka, and Bilitong, and the most recently discovered tin-grounds of 
Australia and Tasmania. The metal is treated in connexion with these 
districts under the various aspects of its geological distribution, the mining 
of the ore, and the history of its production in each locality, the whole 
forming a compendious treatise which has every appearance of being 
thoroughly trustworthy.
