Summary |
Editing the book has been a most interesting task. Even when the authors of a text-book know their subject as well as do the authors of this one, they do not always express themselves logically and lucidly. In the present book the reader cannot fail to be struck with the clearness with which the successive arguments for the adoption of the formulae for the exposed to risk have been set out. The authors are at pains to stress that formulae are not to be learnt by rote but are to be evolved from first principles and devote a considerable portion of the book to the processes for solving the many different types of problem that beset the student in his first approach to the theory and practice of the construction of mortality tables.
