The arithmetical method adopted in these notes is to assume that the level premium to cover a certain under-average life is known; to work out some of the different rates of mortality that might lead to it and then see what consequences follow. The numerical work, in connection with which I have to thank Mr. Sidney J. Perry, F.I.A., for help, will be confined to an unloaded level premium on a 4 per-cent basis of ·01914 for a life entering at age 30. This premium might result from the rates of mortality set out in Table I.
