The latter map, in four sheets, on a scale of about twelve 

 geographical miles to an inch, extending from 2° X. Lat. to 6'' 

 S. Lat., was published in Paris in 1750, under the title Carta

 remainder is largely due to Maldonado. Two different classes 

 of work, of very ditt'erent degrees of value, have been embodied ; 

 namely (1) triangulation of the most precise character, starting 

 from a long and carefully-measured base, checked by a base of 

 verification : and (2) surveys of the rougher kinds, made by the

La Condamine says that Maldonado was a ^^ Creole du Perou."' 

 He was for some time Governor of the district of Esmeraldas, 

 and devoted himself to discovering a more direct road to Quito
