PREFACE. 
Mucu of this paper appeared about two years ago in the Journal of 
the Society of Chemical Industry.* Recently it was communicated by re- 
quest to the Canadian Institute after having been revised and, in a measure, 
brought up to date. A closer scrutiny of the subject matter, however, 
led to the conclusion that entire revisal and rewriting were necessary in 
order that it might present the condition of the chemical industries of the 
Dominion as they are at the time of publication. Every effort has been 
made to do this as far as possible, and the writer hopes that any short- 
comings will be brought to his notice. 
In writing on such a subject as the Chemical Industries of Canada, 
two main considerations have been kept in mind; firstly, that the develop- 
ment of the industrial resources of the Dominion during the past decade 
has been phenomenal, and secondly, that the extent of these developments 
is only fully understood by a few. While it is impossible to discuss all the 
industries in which chemical operations and reactions are made use of, 
an attempt has been made to select processes in some cases peculiar to the 
country, but notably the industries which owe their development to the 
natural mineral and vegetable resources, and to the widely scattered water 
power obtainable in the Dominion. 
The subjects taken up may be classified as follows:— 
I.—Common Salt and Alkali. 
II.—The Extraction and Refining of Metals. 
III.—The Manufacture of Leather. 
IV—Sulphuric Acid, Acetic Acid, Wood Alcohol, Charcoal, and Ammonia 
V.—Soap and Glycerine. 
VI.—Refined Chemicals and Drugs. 
VII.—Fertilizers.
