It is the object of the present article to put together a number of formulae which it may be useful to the actuary to find in one place. At the same time it may show all persons who possess an elementary knowledge of algebra, that they may, with no great amount of tables, and processes of very easy application, learn to compute the value of any benefit in which the duration of one life only is concerned. The same principles, with more extensive tables, apply to cases in which two or more lives are involved.

page 342 note * Actuaries say assurance, and others insurance. The difference may be made useful n i remembering (what the courts of law have not yet found out) that a life assurance and a fire insurance are very different things.
page 346 note * For a given year a proportion of the premiums paid by that time is simply a fixed sum.

page 347 note * In the tables for interests certain it will do equally well to put the payment side forward k years.
