Guy's elements of astronomy, and an abridgement of Keith's New treatise on the use of the globes
A school astronomy textbook by Joseph Guy, combined with an abridgement of Thomas Keith's treatise on the globes, issued in Philadelphia by Key, Mielke & Biddle in 1832 for classroom use. Engraved plates give lettered geometric diagrams: orbits ringed with zodiac signs, hatched and gridded globes, eclipse and shadow constructions, and nested circles of the celestial sphere.
