A MANUAL OF THE ALKALI TRADE,
Including the Manufacture of Sulphuric Acid, Sulphate of
Soda, and Bleaching-Powder. By Joun Lowuas, Alkali Manfacturer,
Newcastle-upon-Tyne and London.
‘* This book is written by a manufacturer for manufaurers. . .
The working details of the most approved forms of apparatus are
given, and theseare accompanied by noless than 232 wood engravings,
all of which may be used for the purposes of construion. . . Every
step in the manufacture is very fully described in this Manual, and
each improvement explained. Such misconceptions as still linger and
retard the satisfactory application of scientific discoveries to the
alkali trade are closely examined, and everything which tends to introduce
economy into the technical details of this trade receives the
fullest attention.” —A thenaum.
“ The author is a prattical man. We find here not merely a sound
and luminous explanation of the chemical principles of the trade, but
a notice of numerops matters which have a most important bearing
on the successful conduét of an Alkali Works, but which are genecally
overlooked by even the most experienced technological authors.
All needless details of an historical or of a purely theoretical character
1ave been judiciously omitted.”—Chemicul Review.
