Robinson Crusoe

From the text:

"About the twelfth day, the weather abating a little, the master made an observation as well as he could, and found that he was in about eleven degrees north latitude, but that he was twenty-two degrees of longitude difference west from Cape St. Augustino; so that he found he was upon the coast of Guiana, or the north part of Brazil, beyond the river Amazon, toward that of the river Orinoco, commonly called the Great River;"
