A Lamp That Will Burn Twelve Months Without Replenishing


Take a stick of phosphorus, and put it into a large dry phial, not

corked, and it will afford a light sufficient to discern any object in

a room when held near it. The phials should be kept in a cool place,

where there is no great current of air, and it will continue its

luminous appearance for more than twelve months.
