PATENT LAMP.
Josiah Warren of Cincinnati is the patentee of a lamp on a new plan. It combines neatness with utility, and possesses one beauty which it is presumed will recommend it to public patronage, viz; to a single family it will produce an annual saving of 20 dollars; to the city of Cincinnati its general introduction would produce an annual saving of 8000 dollars. Its light is clear and pleasant, and the volume of flame equal to that of two common candles. Its structure is such as to fit it equally for the parlour and kitchen.
