A United States government survey report on the geology, paleontology, and natural history of the fortieth parallel, directed by Clarence King with Arnold Hague and Samuel Emmons and printed by the Government Printing Office in Washington from 1870 for scientists and federal administrators. The plates are lithographic specimen studies—here fossil ribs, clavicles, and a jaw arranged in symmetrical rows with small reference numerals—shaded in soft grey tones on pale stock, useful for cut-out bone silhouettes, tapering curved forms, and grid-like specimen layouts.
