A lengthy discursive letter on Isle of Man history, governance, and infrastructure. It traces the island's medieval history (Norwegian, Scottish, English, and Stanley rule), discusses the 1765 union with Britain and its social effects (suppression of smuggling, turn to agriculture), explains Manx coinage and its exchange rates with English and Irish currency, describes passenger routes and travel logistics, and concludes with technical observations on horizontal water-wheels found in the island. The author cites Bishop Wilson and other contemporary sources.
