This ALS was written from the Patent Office in Washington, on May 18, 1861, by the Commissioner of Patents, David Pierson Holloway (1809- 1883), who was also a U.S. Representative from Indiana.  He writes to Charles A. Elliott of Somerville, Mass concerning a patent for gutta-percha coating for warships to protect them in battle.  The letter in regard to the use of gutta-percha or Indian Rubber, was not an unknown item, particularly used in conjunction of ships (and so stated with references by Holloway). Holloway further states that Elliott’s idea is not patentable based on its usage, etc.

The one and a half page letter is on fine condition, and the content is certainly most interesting where gutta-percha is proposed for use on warships. Can’t imagine what problems would have resulted in a heavy naval engagement with hard rubber used against large cannon balls.

Comes with a brief biographical history of Holloway.
