PREFACE
The presentation of essential data concerning vitamines to succeeding
groups of students has become increasingly difficult with the
development of research in this field. The literature itself has assumed a
bulk that precludes sending the student to original sources except in
those instances when they are themselves to become investigators. The
demand on the part of the layman for concise information about the
new food factors is increasing and worthy of attention. For all of these
reasons it has seemed worth while to collate the existing data and put it
in a form which would be available for both student and layman. Such
is the purpose of this little book.
It has been called a manual since the arrangement aims to provide the
student with working material and suggestions for investigation as well
as information. The bibliography, the data in the chapter on vitamine
testing, the tables and the subdivision of subject matter have all been
arranged to aid the laboratory workers and it is the hope that this plan
may make the manual of especial value to the student investigator. The
management also separates the details necessary to laboratory
investigation from the more purely historical aspects of the subject
which we believe will be appreciated by the lay reader as well as the
student.
No apologies are made for data which on publication shall be found
obsolete. The whole subject is in too active a state of investigation to
permit of more than a record of events and their apparent bearing.
Whenever there is controversy the aim has been to cite opposing views
and indicate their apparent value but with full realization that this value
may be profoundly altered by new data.
Since the type of the present manual was set, Drummond of England
has suggested that we drop the terminal "e" in Vitamine, since the
ending "ine" has a chemical significance which is to date not justified
as a termination for the name of the unidentified dietary factors. This
suggestion has been generally adopted by research workers and the
spelling now in use is Vitamin A, B, or C. It has hardly seemed worth
while to derange the entire set up of the present text to make this
correction and we have retained the form in use at the time the
manuscript was first set up. The suggestion of Drummond, however, is

sound and will undoubtedly be generally adopted by the research
workers in the subject.
Attempt has been made to cover all the important contributions up to
April, 1921. Opportunity has permitted the inclusion of certain data of
still later date and undoubtedly other important papers of earlier date
will have been overlooked.
It is a pleasure to acknowledge the assistance received in the
preparation of the manuscript from Dr. H. C. Sherman,
