This layer is a georeferenced raster image of the historic paper map entitled: Map of a portion of South Africa : illustrative of Lieut. Cameron's route from lake Tangayika to the west coast, by E. G. Ravenstein, F.R.G.S. It was published by Geogr. Mag. in 1876. Scale 1:5,000,000. Covers portions of Angola, Democratic Republic of Congo, Rwanda, Burundi, Tanzania, and Zambia. The image inside the map neatline is georeferenced to the surface of the earth and fit to a non-standard 'World Sinusoidal' projection with the central meridian at 20 degrees east. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as expedition routes, drainage, cities and other human settlements, territorial boundaries, and more. Relief is shown by shading. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection and the Harvard University Library as part of the Open Collections Program at Harvard University project: Organizing Our World: Sponsored Exploration and Scientific Discovery in the Modern Age. Maps selected for the project correspond to various expeditions and represent a range of regions, originators, ground condition dates, scales, and purposes.

The analyses of the samples from the Balfour Shoal show that these deposits contain a very large quantity of carbonate of lime, ranging from 88.7 per cent, on the summit to 71.9 per cent, in the deeper water at the base of the cone. The decrease in the quantity of carbonate of lime with increase of depth is not quite regular; still, a general fall in the percentage of lime is clearly indicated from shallower to deeper water. As might be expected in such a circumscribed area, there is a great uniformity both in the chemical composition and relative abundance of the organic and inorganic constituents of the deposits. In all cases the carbonate of lime is almost wholly made up of the dead shells which have fallen from the surface waters - belonging to Plankton organisms such as Pteropods, Heteropods, pelagic Foraminifera and coccoliths. The calcareous shells were in very many cases discoloured brown or black by depositions of the peroxide of manganese. On the north-east steep side of the Balfour Shoal there were indications that depositions of manganese peroxide were more abundant than elsewhere. In 1645 fathoms, there was an angular fragment of a mottled yellowish jasper coated with manganese peroxide, and in 1570 fathoms there were three characteristic spherical black manganese nodules from one-half to three-fourths of an inch in diameter, quite similar to those procured by the Challenger in many areas of the Pacific and Atlantic. In one of these nodules the nucleus was a sub-angular fragment of a light-coloured augite-granophyre.

James Butler Hickok (1837-1876), also known as “Wild Bill” Hickok, was an American gun-fighter, scout and spy. He was involved in altercations with others while working for the famous express company Russell, Majors and Waddell (in 1861), and later while working as a wagon master, scout, and spy for the Union forces during the Civil War. These altercations resulted in the deaths of 4 people, but Hickok was acquitted in all cases. An embellished article written about him in Harper’s magazine helped contribute to his reputation as a western hero. He served as a deputy U.S. marshal and sheriff in Kansas in the late 1860’s, helping to bring law and order to a previously lawless area. He gambled considerably, and during a card game on August 2, 1876, was shot and killed. The cards he was holding (two aces, two eights, and a jack) became known as the "dead man's hand."
