the Comoro Islands, and to one of the two lines predominating on the coasts of southern Africa wherever there are no alluvial flats.’ It abounded, moreover, in minor but significant errors, such as confounding ‘Zanganyika,’ a town or tribe, with Tanganyika, the name of the Lake. Of late years Mr Cooley has once more shifted his position, and has declared that he did not intend to provide central intertropical Africa between ‘Monomotapa’ and Angola with a single lake. The whole of his paper on the ‘Geography of N’yassi’ means that if it mean anything. He is not, however, the only Proteus—hard to find and harder to bind— amongst African geographers. To conclude this notice of the ‘Mombas Mission,’ Dr Krapf again visited Fuga, where he was followed by Mr Erhardt, and finally the two missionaries ran down the coast, touched at Kilwa, and extended their course to Cape Delgado. In August 1855 Dr Krapf, after 18 years’ residence in Africa, bade it farewell; he did not revisit it except for a few months in 1867, when he acted dragoman to the Abyssinian Expedition. In January 1856 appeared what has been called the ‘Mombas Mission Map’ (Skizze nach J. Erhardt’s Original), the result of exploration and of notices collected from the natives. It was accompanied by a ‘Memoir of the Chart of East and Central Africa, compiled by J. Erhardt and J. Rebmann.’ This production was ‘remarked upon’ by Mr Cooley (Jan. 8, 1856), and in turn his remarks were remarked upon by Herr Petermann. The peculiar feature of the chart was a ‘monster slug’-like inland Sea extending from the line to S. Lat. 14°,—an impossible Caspian some 840 miles long × 200 to 300 in breadth. I have already explained that this error arose by the fact that the three chief caravan routes from the Zanzibar coast abut upon three several lakes which, in the confusion of African vocabulary—Nyassa being corrupted to N’yassi, and Nyanza also signifying water—were naturally thrown into one. It was, however, to ascertain the existence of this slug-shaped article that the East African Expedition of 1856-59 was sent out. The most valuable results of Dr Krapf’s labours are his works on the Zanzibarian languages, and these deserve the gratitude of every traveller and student of African philology. The principal are, Messrs Krapf’s and Isenberg’s imperfect outline of the Galla language (London, 1840). Messrs Krapf and Isenberg, ‘Vocabulary of the Galla Language,’ London, 1840. Tentamen imbecillum Translationis Evangelii Joannis in linguam Gallorum, London, 1841. Messrs Krapf’s, Isenberg’s, and Mühleisen-Arnold’s Vocabulary of the Somali tongue (1843). (Three chapters of Genesis translated into the ‘Soahilee’ language, with an introduction by W. W. Greenhough: printed in the Journal of the American Oriental Society, 1847, had appeared in the mean time.) Gospel according to St Luke translated into Kinika, 12mo, Bombay, 1848. Gospel according to St Mark translated into Kikamba, 8vo, Tübingen, 1850.
