ASSISTANT LECTURER ON CHEMISTRY, OWENS COLLEGE, MANCHESTER, &C. London MACMILLAN AND CO. AND NEW YORK 1892 The Right of Translation and Reproduction is Reserved. Reclassi MUP. 6-24-31 PREFACE. WE have much pleasure in recommending this little book to the notice of advanced students of chemistry. Any course of Practical Organic Chemistry leading up to original work in this branch of the science, must mainly consist in the careful preparation of a well-selected series of organic compounds. Dr. Julius Cohen has in the following pages collected such a series, and we feel confident that this work, filling, as it does, a lacuna in our English chemical literature, will prove most useful alike to the Professors, Demonstrators, and Students of our science.
