I was at the Peabody Essex Museum today, and in one of the exhibits I viewed a 17th century Dutch map of the Atlantic. Down the middle of the chart was a longitude scale marked in degrees on the right side. On the left side the markings ran 15 to the degree. I am guessing that at that time, the Dutch had defined the sea league as 4 nautical miles.
Another proposal for Frank: 2 Leagues (American and National) = 1 Major League. This lends itself nicely to decimalization. 1 Degree of a Great Circle = exactly 10 Major Leagues.On Thu, Mar 17, 2016 at 8:41 PM, Don Seltzer <timoneer@gmail.com> wrote:
