PREFACE.
In the field anic chemistry there are a number
of elementary laboratory manuals, any one of which
may be used to the student's advantage. When it
comes to the choice of a guide for an advanced course,
however, there is a vast amount of material available
from which a selection in the form of a laboratory
manual has never been made. Hence the student is
often permitted to follow some line in which he is
interested, regardless of its practicability or its value
from the standpoint of training, or else the planning
of the experiments devolves entirely upon the instructor.
With the object of providing a brief advanced course
in anic chemistry embodying experi-
ments scattered as widely as possible over the important
types of substances and reactions, the author desires
to present this little book in the hope of rendering
simpler the task both of the advanced student and his
instructor.
It has been the writer's aim to select experiments of
greater difficulty than those ordinarily included m ele-
mentary manuals, but to avoid preparations of so diffi-
cult or involved a nature as to e a source of dis-
couragement rather than a stimulus to the student. In
this connection a word of apology may be necessary
for including as much as has been done of the work
of Dr. Walter A. Jacobs of the Rockefeller Institute
and the writer, but it is very strongly felt that the value
of a volume such as the present one depends largely on
the personal experience of its author, and for this rea-
