Page 3 - AN INTRODUCTION TO SURFACE CHEMISTRY By ERIC KEIGHTLEY RIDEAL

•
vi PREFACE

Since this is also the most promising line of advance in the in-
vestigation of disperse systems, Dr Rideal's book can be most
warmly recommended to all who are interested in colloid physics
and chemistry. In the last two chapters the author gives a good
introduction to the principal facts and theories of what is usually
understood to-day as colloid chemistry, so that the reader is fully
supplied with everything that is necessary for a thorough under-
standing of this subject. Every student and investigator of surface
and colloid phenomena owes Dr Rideal a warm debt of gratitude
for his admirable survey and presentation of a great and rapidly
advancing field of physico-chemical science.
