Two drawings made on Carnicobar Island, possibly early in 1786, by the Calcutta merchant Gavin Hamilton (1754-1820), are discussed. One of them has previously been attributed to Robert Hyde Colebrooke so his later visit to the Nicobar Islands is discussed as is the earlier one of Nicola Fontana. Also discussed is the work of Sir William Jones on the Carnicobar breadfruit (Pandanus leram).
