マン島語
Having learned as a young man the Manx language, he devoted much study to the then-neglected language, despised by British authorities. He collected a vast vocabulary and traced its linguistic history. In 1899 he founded the Manx Language Society and became its first president, thus becoming the spiritual forefather of the neo-Manx language movement. He in 1893 edited for the Manx Society for the Publication of National Documents "The Book of Common Prayer in Manx Gaelic", the earliest and longest manuscript in the language.
