His observations to determine the distance of the sun from Earth were continued by Joaquín Velázquez de León, noted astronomer from New Spain. The work appeared in an English edition in 1778.” Palau 67059. Sabin 12003. Wagner, Spanish Southwest 158a. Streeter Sale 2443:
The French government sent out two expeditions to observe the transit of Venus of 1769: one to the Philippines and this one to Baja California, which was accompanied by two Spanish scientists. Chappe d’Auteroche’s account ends on p. 39. The remarks on California are not considered of critical value, but the expedition itself was viewed with such suspicion by the Spanish that it resulted in the dispatch of Gaspar de Portolá in 1769 and hastened settlement of Upper California. Trabulse (Historia de la Ciencia en Mexico, pp. III, pp. 462-466) illustrates title pages to this edition and the English edition, the plates, and provides a partial Spanish translation of the work.
According to most sources, the engraved map of Mexico City probably was based on one by José Antonio Alzate y Ramírez. Toussaint (Planos de la Ciudad de Mexico, pp. 25-26) states that apparently Alzate lent his map to Chappe d’Auteroche when he passed through Mexico City; the map, however, was not up-to-date and appears to show the city as it was before 1750 rather than in 1770. Despite this, Toussaint says it is an important map. Carrera Stampa (Planos de la Ciudad de Mexico 212-213, dimensions incorrect). Illustrated as Plate 138 in Vol. I of Atlas Historico de la Ciudad de Mexico (Mexico City: Smurfit, 1966).
