"Thts book is written by a manjjfacturer for manu'acturers. The working details of the most 

 approved fonns of apparatus are given, and these are accompanied by no less than 2^2 wood en- 

 gravings, all of which may be used for the purposes of construction. Every step in the nianufai - 

 ture is very fully described in this manual, and each improvement explained. Everything which 

 tends to hitroduce economy into the technical details of this trade receives the fullest attention. " — 

 .It/tenceinn. 



"The author is not one of those clever compilers who, on short notice, wiM 'read up "any conceiv- 

 able subject, but a practical man in the best sense of the word. AVe find here not merely a sound 

 and luminous explanation of the chemical principles of the trade, but a notice of numerous matters 

 which have a most important bearing on the successful conduct of alkali works, but which are 

 generally overlooked by ereu the most experienced technological authors." — Chanical Review.
