TRANSLATOR'S PREFACE
THE ess of Professor Gattermann's book in the original
has warranted its reproduction in English. The translation is
intended for those students of chemistry who have not yet
e sufficiently familiar with scientific German to be able
to read it accurately without constant reference to a dictionary.
To such students this translation is offered, in the hope that it
will increase their interest in the science without causing a cor-
responding decrease in their efforts to acquire a knowledge of
German, which is indispensable to every well-trained chemist.
My grateful acknowledgments are due to my colleague, Dr.
H. M. Ullmann, for many valuable suggestions, and to Professor
Gattermann for his courtesy in pointing out several uracies
in the German edition.

frequently impossible, even with the best intentions, to direct the
attention of each individual to the innumerable details of labo-
ratory methods. In order that students, even in the absence of
the instructor, can gain the assistance necessary for the carrying
out of mon operations, a
