The description of the remaining portions of the coast is derived from the running surveys of the late Captains W. F. W. Owen and A. T. E. Vidal, R.N., 1823-25; from the observations of Captain de Horsey; the remark books of officers of H.M. Ships, and other documents in the Hydrographic Department, Admiralty. The longitude of places given in the text of this work between the cape of Good Hope and Delagoa bay depend upon Cape observatory being in 18° 28′ 45′′ E. of Greenwich. The longitudes between Delagoa bay and Kisimayu (Refuge bay) depend upon Zanzibar (British Consulate) being in 39° 11′ 11′′ E. (By the latest determination, the Cape observatory is considered to be in long. 18° 28′ 40′′ E., and Zanzibar in long. 39° 11′ 8′′ E., but as these are not final, places dependent on them have not been altered). Between Kisimayu and cape Guardafui the longitudes depend upon Aden (local telegraph office) being in 44° 59' 7" E. of Greenwich. The first edition of this work compiled by Captain A. F. R. De Horsey, was published in 1864. The second edition in 1865. The third edition was revised by Commander J. Penn in 1878. The fourth edition with an appendix was published in 1884.
