other natural causes upon the nature of these productions, and 
briefly noticing the chief forms of produce which commerce derives - 
from each country. The second part is devoted to the commercial 
produets of the vegetable kingdom, the third to those derived from 
the animal kingdom; and the fourth treats of mineral products. 
Under each of these heads the subjeets are arranged in accordance 
with the uses to which they are put; and in each case the sources 
of the different commercial substances are indicated, and their com- 
mercial statistics are given, generally, as far as this country is con- 
cerned, up to the year 1867. As a general rule, these articles are 
very accurate; but here and there, as perhaps was unavoidable in a 
first attempt like this, small errors have crept in. Thus,for example, 
under the head of ** furs,” we are told that furs are obtained from all 
the orders of Mammalia except the Bimana and Cetacea. Apart 
from the fact that all the skins enumerated by the author are not 
furs in the true sense of the term, the Pachyderms certainly furnish 
us with nothing that can be denominated a fur: an elephant-muff 
or a rhinoceros-tippet would be rather a striking novelty. Again, 
under the same head, there is an important omission: the only 
seals noticed are the northern species, and the true fur-seals are 
entirely unnoticed. The account of the natural history of the hive- 
bee is nct quite what it should be, and might be considerably im- 
proved without adding to the space it occupies; and the description 
of the commercial products of the lac-insect is confused, and does 
not clearly indicate that the dye is the produce of the insect itself, 
whilst the shell-lac is an exudation from the tree. 
Apart from the few inaccuracies above alluded to (the most im- 
portant one that we have noticed being the omission of the fur-

ngnages ; it may prove useful to others besides those for whose 
special behoof this book was written. 
We should add that this is the first of a series of three works on 
the same subject, of which one will be devoted to the industrial and 
political history of commerce, and the second to the technical history 
of the same subject.
