thereon the usual records referring to the zodiacal constellations and to the time reckoning. This horizon circle rests upon four supporting arms or quadrants, which in turn are carried by a tripod base of wood. The spheres are of pasteboard with plaster of Paris covering, on which the respective maps have been pasted, each map being composed of twenty-four gores or biangles, or of twice twenty-four, since each is cut on the line of the equator to facilitate mounting. The geographical records given on the terrestrial globe map are practically such as one could find on the best plane maps of the period, always, however, in this connection remembering that those regions which had not been visited or carefully charted by explorers gave to the map maker considerable latitude for a play of his imagination. It is interesting, for example, here to note that Adams appears to have been very uncertain about his information relative to the western and southwestern part of the present United States. He seems to have caught from some explorer’s account that the Colorado River flows westward, emptying directly into the Pacific, and he so marks it, giving, however, to the river the name St. Bartholomew. The celestial globe revolves on the axis of the equator, the gores being made to terminate at the poles of the ecliptic. Constellations are represented so far as they have been named by astronomers to date, the several figures being artistically drawn, on which color has been somewhat sparingly employed. Each constellation is given its old name with an English translation; star names, when given, are frequently in Arabic, Latin or Chinese, and are distinguished by Greek letters. Recently discovered stars are so marked as to be easily distinguished. In addition to the above, a pair of Adams globes may be found in the Osservatorio Astronomico of Naples and a pair in the Biblioteca Classense of Ravenna. A copy of the terrestrial may be found in the Seminario Vescovile of Padua. A copy of the terrestrial dated 1785 may be found in the Biblioteca Real of Madrid, agreeing in general with the preceding except in the mounting. The author and date legend appears in a neat cartouch in the North Pacific, reading: “Britanniarum Rigi Augustissimo Georgio Tertio Scientiarum Cultori pariter et praefidio Globum hunc Terrestrem. Omnes hactenus exploratios terrarum tractus. Ad Observationes Navigantium Itinerantium et Astronomorum recentiores, accuratissime descriptos exhibentem Grati animi et pietatis monumentum D. D. Q. Omni cultu et officio devinctissimus. G. Adams. Londini apud G. Adams artificem regium in vico (?) Fleet Street, 1785.” [Illustration: Fig. 130. Terrestrial Globe of George Adams, 1782.]
