Marcus Bull (1787-1851) was a member of the American Philosophical Society who published a paper in 1826 of his experiments with wood and coal fuel made in 1823. Bull then applied for a premium from the American Academy of Sciences at Boston who were trustees of a fund endowed by Count Rumford, a prize to be awarded to the inventor of the most useful discovery of heat and light. Bull's experiments were deemed of questionable merit. Thus began this pamphlet controversy in which Bull herein defends his research and conduct. Bull reprints numerous letters between himself and Jacob Bigelow at the American Academy of Sciences. A nod from Benjamin Silliman is also included. Rumford's original letter to President John Adams is reprinted within.
