West is "up" when in reading position. The graphic scale bar unit of measure is toises (1 toise = 6ft.). The scale calculated and rounded from 1:7,938. No geographic coordinates displayed / no graticule / no indication as such of a prime meridian. Rhumb lines displayed for navigation, magnetic north indicated with fleur de lis symbol. The presence of rhumb lines indicates a conformal projection, likely Mercator's, which preserves shape and direction, for the purpose of navigation.

The presence of the number 19. in red outside the neatlines ties this to the Neptune Americo-Septentrional contenant les côtes, Paris, 1778-80. It is most likely the 1780 edition as Kershaw documents the 1779 edition and does not describe the number 19 in red.
