On the title page of his _Naturalist's Sojourn in Jamaica_, as well as in his preface, Gosse bears testimony to the assistance which Hill rendered to him. The appearance of Hill's name on the title page ("Assisted by Richard Hill, Esq., Cor. M. Z. S. Lond., Mem. Counc. Boy. Soc. Agriculture of Jamaica") was, Mr. Edmund Gosse tells us in his memoir of his father, greatly against that modest gentleman's wish. He tells us also that the friendship for Hill was one of the warmest and most intimate friendships of his father's life. The publication of this book was delayed by the fact that every sheet was sent to Spanish Town to be read by Hill. Hill contributed to several scientific publications both in England and America and by this means became connected with some of the leading learned societies of the world. He was corresponding member of the Zoological Society of London, of the Leeds Institute and of the Smithsonian Institution, and he numbered amongst his correspondents Darwin and Poey. Darwin had written in September, 1856, to Gosse for further information with respect to the habits of pigeons and rabbits referred to in his _Sojourn_, and it was at Gosse's suggestion that Darwin wrote to Hill. In a later letter, of April, 1857, he says: "I owe to using your name a most kind and valuable correspondent in Mr. Hill, of Spanish Town." The cony of Jamaica, _Capromys brachyurus_, found commonly in his day, but now becoming extinct, was named by Hill in Gosse's _Naturalist's Sojourn_; as well as four birds--three in the _Birds of Jamaica_ and one in the _Annals and Magazine of Natural History_, and two fishes. One bird (_Mimus hillii_), two fishes and four mollusca, three being Jamaican, were named after Hill. In addition to his collaboration with Gosse of the _Birds of Jamaica_ and the _Naturalist's Sojourn in Jamaica_, Hill's best-known literary productions are _A Week at Port Royal_, published at Montego Bay in 1858; _Lights and Shadows of Jamaica History_, published in Kingston in 1859; _Eight Chapters in the History of Jamaica, 1508-1680_, illustrating the settlement of the Jews in the island which appeared in 1868; and _The Picaroons of One Hundred and Fifty Years Ago_, which was published in Dublin in 1869. He contributed, moreover, a large number of articles on natural history subjects to various Jamaica publications too numerous to mention. Some of these were: _The Jamaica Almanacs_; _Transactions of the Jamaica Society of Arts_; _Transactions of the Royal Society of Arts of Jamaica_; _The Jamaica Physical Journal_; _Jamaica Monthly Magazine_; _Jamaica Quarterly Magazine_. In England he contributed to the _Proceedings of the Zoological Society_; and in America to the _Proceedings of the Academy of Natural Science_, Philadelphia, and the _Annals of the Lyceum of Natural History_, New York.
