Excerpt from A Treatise on Cosmospherically Mounted Terrestrial and Celestial Globes: For Self-Instruction and for Schools, With an Appendix on the Use of Cosmospherically Mounted Globes, of an Orbography, of a Loxodromograph, and of a Spherometer, Instruments for Calculating, the Latitude and Longitude at Sea Sec.1. - The common manner of mounting a terrestrial and a celestial globe limits the use of both to the solving of a few of the most common problems, not mentioning the inconveniences experienced in applying them for explaining some subjects or other of geography and astronomy. And the unnatural position of a part of the stand of a globe, mounted in the common manner, or of a plane or ring of wood round their surface, the centre of which is to be in the centre of the globe, and which is to show the horizon corresponding to any part of their surface, is the greatest objection; as, after adjusting the horizon to a certain point, an idea of a motion of the globe will put every part out of its relative and true position. II. The free suspension of cosmospherically mounted globes allows them, however, to swivel free round their centre in any direction required, while they avoid the unnatural representation of the horizon, which, if adjusted to any point of the surface of a cosmospherically mounted globe, will swivel round with it, and allow the solving of problems in astronomy and geography, which hitherto were considered impracticable for common mounted globes.
