In this SOCIETY are combined the ADVANTAGES of Mutual Assurance with Moderate Premiums. The Premiums are so moderate that at most ages an Assurance of £1,200 or £1,250 may generally be secured from the first for the same yearly payment which would elsewhere assure (with profits) £1,000 only.
The Whole Surplus goes to Policyholders on a system at once safe and equitable, no sbare being given to those by whose early death there is a loss.
