would certainly have been much smaller in the Manchester Unity Experi- 
ence, it would necessarily have as its consequence more linking-up, and 
therefore more short attacks paid at the disablement rate. In the 
nature of the case this feature would be of less importance at 
ages over 40 than at the younger ages. The experience at ages over 40 
appears, in fact, to confirm the corresponding experience in respect of 
sickness benefit. 
7. The average duration of disablement claims within the year is shown, 
in weeks, by Table 3.

8. The average duration within the year is, of course, substantially less 
than the total duration of disablement benefit, since cases of prolonged 
disablement may extend over several years. In consequence the differeaces 
in average duration of claim in the two experiences are somewhat masked 
in the figures shown above. 
By making certain assumptions it is possible to calculate approximately 
the average total duration of disablement claims, and the resulting figures 
are shown, in weeks, in Table 4 below.

9. As might be anticipated the figures confirm those of Table 8, and 
emphasise the striking differences between the Manchester Unity Experi- 
ence and that of the Selected Societies.
