Congress having referred to me a petition from a person of the name of Isaacs, setting forth that he has discovered an easy method of rendering sea-water potable, I have had a cask of sea-water procured, and the petitioner has erected a small apparatus in my office, in order to exhibit his process.

Although no texts have been found and none is recorded in SJL, it is virtually certain that similar requests were made of Caspar Wistar, Jr. and David Rittenhouse (see TJ’s report, 21 Nov. 1791).
