Samuel Augustus Mitchell (1790-1868) was an American geographer born in Connecticut. He first worked as a teacher before eventually focusing his time on publishing geographical maps and textbooks, a subject he had become involved in after realising that what geographical resources available to teachers were of poor quality. He moved to Philadelphia in either 1829 or 1830, where he founded his company, publishing materials that covered all genres of geography.
United Kingdom: Map of the World showing the British Empire highlighted in red, London, 1886. The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom. It originated with the overseas colonies and trading posts established by England in the late 16th and early 17th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power.
Procamelus had long legs designed for speed, and was about 1.3 metres (4.3 ft) in height, slightly smaller than a modern llama. Unlike modern camelids, it had a pair of small incisor teeth in the upper jaw. The remaining teeth were large and adapted for eating tough vegetation. The shape of the toes suggests that it possessed foot pads, like modern camels, but unlike earlier forms of camelid, which generally had hooves. This would have helped it walk over relatively soft ground.
