		Napier's bones were described in his book Rabdologie, which was published in 1617, shortly after his death.
		Although the bones often seem to be confused with his logarithms, there is in fact no connection and the bones represent an application of the old Arabic lattice method of multiplication.
		Strictly speaking, the bones do not act as a calculating device in the modern sense of the word but merely serve to enforce the correct use of the lattice algorithm.

	John Napier at AllExperts
		John Napier or Neper, nicknamed Marvellous Merchiston (1550–April 4, 1617) was a Scottish mathematician, physicist,astronomer/astrologer and eighth Laird of Merchiston.
		He is most remembered as the inventor of logarithms and Napier's bones, and for popularizing the use of the decimal point.
		Napier is relatively little-known outside mathematical and engineering circles, where he made what is undoubtedly a key advance in the use of mathematics.

	Visible Storage
		Napier’s Bones are portable single-digit multiplication tables that can be arranged to show the product of multiplying almost any multi-digit number by a single digit.
		Although John Napier invented them in the late 1500s, a description of the “bones” was only published at the end of his life, in his book Rabdologiæ, because he was concerned that others would take credit for his idea.
		Although Napier is widely credited with their invention, Jobst Burgi, a Swiss maker of mathematical instruments who worked closely with astronomer Johannes Kepler, independently developed logarithms.

		Napier Bones in Various Bases John Napier (1550-1617), a Scottish mathematician, is mostly known for his invention of logarithms - a device that revolutionized calculations by reducing difficult and tedious multiplication to addition of table entries.
		In 1617, three years after appearance of Mirifici logarithmorum canonis descriptio (A Description of the Wonderful Law of Logarithms), he published Rabdologiae which was recently reproduced as Rabdology by the Charles Babbage Institute in the Reprint Series for the History of Computing.
