Derrotero de las islas Antillas (Direccion de Hidrografia, third edition, Madrid 1837)

The Spanish state hydrographic office's sailing directions for the Antilles, the coasts of Tierra Firme and the Gulf of Mexico, printed at Madrid in 1837 as companion to its own charts. Its opening notice states what an official publication need not state: that the elements used do not all merit equal confidence, that reports of the same place disagree, and that the book is far from perfect - and it puts every Spanish pilot under standing order to send the errors back.
