Notice of Josiah Warren's lard-lamp patent

"Weekly Summary," The Plough Boy, and Journal of the Board of Agriculture, 2, 52 (May 26, 1821), 415.

Josiah Warren, of Cincinnati, is the patentee of a lamp on a new plan, which is said, to a single family, will produce an annual saving of 20 dollars. Its light is clear and pleasant, and the volume of flame equal to that of two common candles.
