during the last decade, the Soap Industry has not

anything of a very revolutionary character, steady
progress has still been made in practically all
branches, and the aim of the present work is to describe
the manufacture of Household and Toilet Soaps as carried
out to-day in an up-to-date and well-equipped factory.

with the principles of elementary chemistry is assumed,
and in this we feel justified, as in these days of
strenuous competition, no soap-maker can hope to compete
successfully with his rivals unless he has a sound
theoretical as well as practical knowledge of the nature
of the raw materials he uses, and the reactions taking
place in the pan, or at other stages of the manufacture.
We also venture to hope that the work may prove useful
to Works' Chemists and other Analysts consulted in
connection with this Industry.

knowledge is necessary, the subject being treated in
such a way that it is hoped those who are not directly
engaged in the manufacture of soap, but who desire a
general idea of the subject, will find it of
