	Edmund Gunter
		Gunter, Edmund (1581-1626), was of Welsh extraction, but was born in Hertfordshire in 1581.
		Gunter's Line, a logarithmic line, usually laid down upon scales, sectors, etc. It is also called the line of lines and the line of numbers, being only the logarithms graduated upon a ruler, which therefore serves to solve problems instrumentally in the same manner as logarithms do arithmetically.
		Gunter's Scale (generally called by seamen the Gunter) is a large plane scale, usually 2 feet long by about 1-1/2 inches broad, and engraved with various lines of numbers.

	NMAH \| Navigation \| Gunter Quadrant
		Edmund Gunter, an English mathematician, described this type of pocket-sized instrument in 1618.
		The Gunter quadrant is unique in that it is also imprinted with projections of the tropics, equator, ecliptic and the horizon.
		The Gunter quadrant was cheap, portable, and compact, but because its scales and lines applied to only one specific latitude, it was primarily used on land.
