FIRST EDITION OF ONE OF THE GREATEST BOOKS ON PRACTICAL NAVIGATION. On his voyage in 1800, the skilled navigator and mathematical prodigy, Nathaniel Bowditch discovered numerous errors in the existing navigational literature in use at the time. He discovered that the various English Navigators then in use had been calculated on the erroneous assumption that 1800 was a leap year, causing his ship to go 23 miles off its course. Rather than further revising new editions on the subject, Bowditch decided to write a new book on his own. "The result was this, the best book of its kind in English ... [it] was the first complete epitome of practical navigation for the common man, and was at once acclaimed by the maritime world ... Often termed the greatest book in all the history of navigation, this intellectual achievement of our early culture was indispensable to the maritime and commercial expansion of the nineteenth century" (Grolier/American).
