PREFACE
The principal object in preparing a compilation of solubility
data, from the point of view of the advancement of chemistry, is
to furnish material for the origination and verification of theories
of solution. The majority of investigators who have been en-
gaged on such problems, have been compelled to determine ex-
perimentally the values required for developing the generalizations
they hoped to establish. In fact, a large part of the most accurate
data which are here brought together, are the outgrowth of such
studies. It is hoped, therefore, that the present effort to make
these and all other quantitative results more accessible for theo-
retical studies of solubility, will lead to noteworthy advances in
this field of chemistry.
Of the various properties which determine the uses of com-
pounds in a chemical way, solubility is of first importance. There-
fore, solubility data are perhaps of even greater interest from a
practical than from a theoretical point of view. For this reason it
has been necessary to consider the needs of those who require such
information only incidentally and may, therefore, be less familiar
with some of the forms used for its expression. With this in
mind, and at the suggestion of users of the preceding edition,
chapters have been prepared in which are described, among other
things, the sources of solubility data, the methods of calculating
them to desired terms, the interpretation of their tabular arrange-
ment, as well as some of the methods used for the accurate deter-
mination of solubilities.
Soon after the previous edition was issued, the collection of the
new data, to be used in keeping the subject matter up to date,
was systematically begun. In doing this, the experiment was
made of examining each journal page by page, instead of scan-
ning the titles of original papers contained in it. This resulted in
the discovery of many data that would otherwise have been over-
looked, and it soon became apparent that a more careful search of
the literature than that previously made was necessary. It was,
therefore, decided not only to examine the current periodicals
minutely, but to go through the back volumes in a manner equally
asthorough. Thedatacollected in thiswaysoon amounted to more
than could be advantageously added as a supplement to the tables
in the first edition, and it was decided to wait until the whole
book could be completely rearranged, before making any additions

to the subject matter. It also appeared advisable to extend the
scope to include freezing-point and certain other data, which had
been omitted entirely from the first edition. The undertaking,
therefore, developed far beyond the original expectation of regu-
larly adding, from year to year, the new data which would keep
the compilation up to date. Since the amount of time at my dis-
posal for this work was limited, progress necessarily has been
slow. Finally, the advent of the war extended the period far be-
yond the limit caused by other conditions.
Although the compilation has now been completed, I realize
that in a work of this kind, more satisfactory results would have
been achieved if several individuals had cooperated in its prepara-
tion. The recent decision of the American Chemical Society to
extend its activities to the publication of reference books, will, I
hope, insure that hereafter, compilations of the present character
will be made in the exceptionally thorough manner which only an
organization with elaborate facilities can provide.
In this connection I wish to express the opinion that the new
venture of publishing compendia of chemical literature, which the
chemical societies of England and America are just now about to
undertake, will prove of service to the progress of chemistry in
English speaking countries, second only to that rendered by the
journals of original and of abstract literature, which these societies
have so successfully developed.
I realize, more than ever, that opportunities for the occurrence
of errors are innumerable and although I have endeavored to
maintain unremitting vigilance to avoid them, my efforts toward
this end have not always been successful. I desire to express my
appreciation to all who have called attention to errors in the
former edition and I will be equally grateful to those who point
out to me needed corrections in the present book. In this con-
nection, I am greatlyindebted to Professor B. N. Menschutkinof the
Polytechnic Institute (Sosnovka), Petrograd, Russia, who, in calling
my attention to an error in the tabulation of some of his work
given in the first edition, sent me a complete set of reprints of his
many papers on solubility and personally corrected the tables
which I prepared from them, for use in the present volume.
In conclusion I wish gratefully to acknowledge the assistance
rendered me by Dr. W. S. Putnam of the Cooper Union of New
York during the compilation of the first 150 pages of the tables.
