A letter from Colonel David Humphreys to Sir Joseph Banks, read to the Royal Society in January 1813, describing the Ancon or Otter breed of sheep. The breed began in 1791 in Dover, Massachusetts, from a short-legged lamb born to Seth Wight's flock. The letter covers the breed's inheritance, crossing with common and Merino sheep, fleece quality, physical weaknesses, a dissection by Dr. Shattuck, and its decline after Merinos were introduced into New England.
