PREFACE.
The aim of the following handbook is two-fold; to give, in acompendious form, such a summary of our scientific knowledgeas may be useful to the practical tanner; and such asketch of manufacturing processes as may enable the chemistto apply his knowledge to their improvement. Each may,therefore, find some superfluous matter, for which his indulgenceis asked. The book is an expansion of a short articlewhich appeared in Spons' 'Encyclopædia of the IndustrialArts,' and to some extent still bears traces of its origin;and, having been written under stress of limited leisure,and defective eyesight, is very far from being so perfect asI should desire. For the sake of completeness it has beennecessary to describe many processes which are outside therange of my own manufacturing experience, and in doingso I have generally referred to the sources of my information.Chapters III. and XXIV. are written by Mr. C. G. WarnfordLock, to whose kind assistance I am much indebted. It maybe well to state in conclusion, that while the work is notintended for a cram-book for technical students, it is hopedthat it may be an assistance to teachers of the subject.
