REVIEWS—THE MANUFACTURE OF VINEGAR. 183 
the industry, trading, and missionary enterprise, of the various 
districts explored, are all treated of in detail. Indian customs, 
superstitions, and general characteristics, as well as the history of the 
curious mixed population growing up within the Company’s territories, 
supply materials for another series of chapters; while a third is 
devoted to the geological and paleontological characteristics of the 
country explored. Numerous illustrations add to the minuteness and 
value of those details; and combine to form a work which ought to 
find a place in every public library in Canada. D. W. 
The Manufacture of Vinegar ; its theory and practice. By Charles 
M. Wetherill, LL.D., M.D., &c. &e. Philadelphia: Lindsay and 
Blackiston. 
Vinegar is a substance which is used so extensively both in 
domestic life and in many of the useful arts, that its cheap and 
certain manufacture has of late years become a subject of considerable 
importance. For persons requiring any large amount of vinegar in 
their domestic economy, and especially if living at any great distance 
from towns, the knowledge of a sure process of manufacture is very 
desirable, not only on account of a possibility of a failure in the 
supply, but also on the score of economy. Vinegar even for 
domestic purposes is used in large quantities, especially in the prepa- 
ration of those hideously indigestible pickled cucumbers which form 
so frequent an addition to the dinner table on this continent, and 
being a bulky article, containing but little of the acidifying principle 
in comparison with the water, the cost of transport becomes con- 
siderable, and the marketable price far beyond that for which it can 
be manufactured in every private farm house. A few pounds of 
starch obtained from damaged wheat, from Indian corn, from potatoes 
(even diseased ones,) or a like quantity of sugar obtained from the 
maple or the sorghum, or even a gallon of unrefined maple or sorg- 
hum molasses, will, with proper management, yield an amount of 
excellent vinegar, which in most country places could only be 
purchased by the expenditure of many dollars. 
The above mentioned work is well calculated to afford all necessary 
information on the subject, not only to the manufacturer in the 
larger towns, but also to the Paterfamilias of our rural districts. 
Many treatises have been written on the subject, among which none
