Life insurance is an admirable system, devised, in all its ramifications, to provide against loss or damage through the various contingencies to which human nature is subject. A simple life insurance is that by which a person may leave behind him a sum of money for the benefit of those who, during his life, have been dependent upon him. For example, a husband, whose income is entirely derived from his own exertions, desires to make some provision for his wife and children in the event of his dying before them.
