FIRST EDITION IN FRENCH, THE FRANK S. STREETER COPY, with the Paris imprint on the title which appears in some copies. According to Sabin, no copies were printed at Paris, but all were printed in Paris and Leipzig by Arkesee and Merkus.  Ulloa and Juan, officers in the Spanish Navy, were attached to a French expedition organized by the Academie des Sciences to South America, and on their return to Spain in 1746, they compiled the present work, with Juan writing the scientific observations, and Ulloa writing the historical aspect of the expedition. 

THE WORK INCLUDES THE EARLIEST RECORDED REFERENCE TO THE "AURORA AUSTRALIS." Sabin calls for only 45 plates, and copies are recorded in American Book Prices Current with totals ranging from 45-55. The large map of Quito is three joined plates.  Hill 1740; Howgego U3; Palau 125473; Sabin 36812.
