The “graphic” method of constructing a Life-Table which is ably and lucidly expounded in the paper by Drs Newsholme and Stevenson (published in the Journal of Hygiene, vol. III. No. 3, pp. 297—324), is one way of dividing up foundation figures of population and deaths, given in groups of ages, into numbers belonging to each separate year of age, so that, either directly by the fraction , or indirectly by first obtaining , and then finding the value of , the series of px values is obtained forming the connecting link between the data and the results of the Life-Table.
