Where a member or person claiming through a member of a society is insane, and no committee of his estate or trustee of his property has been duly appointed, the society may, when it is proved to the satisfaction of the committee that it is just and expedient so to do, pay the amount of the shares, loans, and deposits belonging to such member or person, to any person whom they shall judge proper to receive the same on his behalf, whose receipt shall be a good discharge to the society for any sum so paid.
