"A Letter to a Royal Academy" was composed in response to a call for scientific papers from the Royal Academy of Brussels. Franklin believed that the various academic societies in Europe were increasingly pretentious and concerned with the impractical. Revealing his "bawdy, scurrilous side," Franklin responded with an essay suggesting that research and practical reasoning be undertaken into methods of improving the odor of human flatulence.

The essay was never submitted but was sent as a letter to Richard Price, a Welsh philosopher and Unitarian minister in England with whom Franklin had an ongoing correspondence.

The essay discusses the way different foods affect the odor of flatulence and to propose scientific testing of farting. Franklin also suggests that scientists work to develop a drug, "wholesome and not disagreeable", which can be mixed with "common Food or Sauces" with the effect of rendering flatulence "not only inoffensive, but agreeable as Perfumes".
