Original Message:
One of the real gems among the gold mine of 18th century navigation
documents that everyone has been downloading is Margetts' Longitude Tables
by George Margetts, published in 1790. "Tables" was probably a poor choice
for a title as the collection is really a series of graphs allowing one to
clear a lunar distance by interpolating the necessary corrections.
