Near the first legend has been pasted the following brief printed statement, “Propter motum, Stellarum fixarum versus ortum post annum 1750 additione 3/4 gr. Correctio Longitudinum ut instituatur monendus Uranophilus.” “Because of the movement of the fixed stars toward the east since the year 1750, the student of astronomy is advised to correct the longitude by the addition of 3/4 of a degree.” The terrestrial globe map, composed of eighteen gores, is filled with interesting geographical details, with geographical names and brief explanatory legends, being a fine example of the superior cartographical work published in that century in the Netherlands. There is something of an exaggeration in the representation by waving line of the several coasts and river courses, all of which appears to have been done for artistic effect rather than for a desire to be strictly accurate. In the New World we find such regional names as “Penn-Sylvania,” the first part of the name being north of Lake Ontario, also “Carolina,” “Virginia,” “Belgia Nova,” “Anglia,” “Scotia Nova.” Many provincial names are given in South America with boundary lines drawn. California is represented as an island, stretching northward to “Fretum Aniani.” To the west of this stretches as far as the northeast coast of Asia, through about seventy-five degrees of longitude with definitely drawn southern coast line but extending indefinitely northward, a continental region bearing the legend “Terra incognita sive terra Esonis.” Loxodromic lines are represented as on the best globes of the period radiating from numerous compass roses located along the meridians 0 degrees, 180 degrees, and 270 degrees. Frobisher’s Strait is strangely duplicated at the southern extremity of Greenland. The title legend of this terrestrial globe, placed in the southern Pacific, reads, “Universi Orbis Terrarum Facies cum industria ac fide Secundum certissimas et novissimas Praestantissimiorum Geographorum Observationes denuo luci exposita; cuique praeterea longitudinis et latitudinis gradus Secundum Uranographiam novam, ac proinde &c. rei veritate sunt inscripti per Gerhardum et Leonhardum Valk, Amstelaedamenses 1750, cum privilegio.” “A representation of the land of the whole earth exhibited with industry and accuracy according to the most reliable and the most recent observations of the most renowned geographers, on which, in addition the degrees of latitude and longitude according to a new method and also in accord with truth, have been inserted by Gerhard and Leonhard Valk. Amsterdam. 1750. With privilege.”
