PREFACE
In the following pages we have attempted to describe,
with as little technicality as possible, the usual
methods of constructing mortality and similar tables.
As this book is intended mainly for those who have
little or no acquaintance with the subject, we have
tried to explain each step verbally with the help of
arithmetical examples, in order to avoid the introduc-
tion of algebraical formul*. It seems to us that such
formula are of little use in explaining the principles
of the subject to beginners.
We
have tried to avoid debatable points, but we
feel that in some directions the subject has not yet
been advanced beyond the empirical stage. This is
particularly true of the treatment of census data.
Much work has been done in perfecting the details
of the census methods, but their bases rest on very
weak foundations, and it seems that until fuller and
more accurate information is available the value of
the assumptions at present made cannot be properly
determined.

In conclusion, we desire to record our indebtedness
to our friend J. A. Humphreys for many valuable
suggestions. He most kindly offered to read the
book again in proof, but his sudden death has de-
prived us of this further help.
