The maps on these globes present no features of special scientific value, the author following in the main the best contemporary geographical and astronomical records. It should, however, be noted that he introduced an improvement in the construction and printing of the circular polar discs. To the end of remedying the difficulty in attaching this part of the covering, having observed, as others, that the paper would expand with the application of paste, and could therefore not be adjusted with the strictest accuracy and nicety, he conceived the idea of cutting from this disc a very small section or small sections, so that when it was applied to the sphere after being moistened with the paste the amount of stretching was sufficient to cover the space. In other words, he made his circular disc one of 350 degrees instead of one having the full 360 degrees. In this connection, it might be noted that the quality of the paper was an element always to be taken into account in calculating the amount of expansion after moistening. A pair of Seutter’s globes may be found in the Biblioteca Comunale of Macerata. A copy of the terrestrial is reported in 1892 to have been in the private library of Professor Maximilian Tono of Venice, a pair in the Museo Astronomico of Rome (Figs. 124, 125) and also in this museum may be found a complete set of the gores for one of his terrestrial as well as a set for one of his celestial globes, but which by Professor Jacoli of Venice have been thought to be reprints and not originals. A copy of the celestial globe may be found in the Biblioteca Universitario of Urbino. [Illustration: Fig. 124. Terrestrial Globe of Mattheus Seutter, 1710.] [Illustration: Fig. 125.

Terrestrial Globe of Van Lauen Zonen, 1745.] Robert Morden,[144] active in London in the closing years of the seventeenth and early years of the eighteenth century as map and globe maker, seems, however, not to have won for himself a place of particular prominence, his maps not being held in especially high repute. He was for some time associated with Thomas Cockrill at “The Sign of the Atlas” in Cornhill. Morden, however, published a small work on geography and navigation in the year 1702, in which he attempted to set forth the value attaching to globes for those interested in the general subject of which he treated in his work.[145] While his map publications are numerous, it has been possible to locate only the gores of one of his globes, which gores may be found in the British Museum. Of the twelve sections which made up a complete set for covering a sphere about 35 cm. in diameter, but nine remain, three having disappeared.
