In the year 1853, Kalli rendered essential Service in the preparation of a Greenland Esquimaux Vocabulary, for the use of the Arctic Expedition of that year. The work was printed by direction of the Lords of the Admiralty, with a short Preface acknowledging the advantage of his assistance. Captain Washington, R.N., Hydrographer of the Admiralty, says in the Preface, "Every word has now been revised from the lips of a native. In the Midsummer vacation in 1852 Kallihirua passed some days with me, and we went partly over the Vocabulary. I found him intelligent, speaking English very fairly, docile and imitative, his great pleasure appearing to be a pencil and paper, with which he drew animals and ships. At the Christmas holidays, we revised more of the Vocabulary, &c."

A member of the Expedition afterwards visited St. Augustine's College and stated that the Vocabulary had been found to be of much service.
