This collection of a series of fourteen articles from The Geographical Magazine (London) by the Keeper of the Map Room of the British Museum discusses the maps used or drawn by the explorers themselves, from the 15th to the 18th century. The abundance of maps and many other contemporary illustrations make this a handsome book. Geographical discoveries are divided into East, West, North, the Spice Islands and Cathay, the South Sea, the Continents and the Poles, the ideas and events, the motives and objectives are tied into the maps reproduced. Each chapter has separate sections of remarks on the illustrations and notes; there is a bibliography of collections of voyages and travels published before 1700, and an indez. The whole reflects the growth of geographical knowledge, ""what the traveller expected to find or what he in fact discovered"", and should offer fascinating study for those whose interests are in cartography and geography.
