[From Introduction to Eighth edition] THE great activity in our field of research, the increasing number of laborers in it, and the rich gleanings from it, have made necessary a recast of this work. With new lights and better materials, I have not hesitated to tear down and build up anew whenever they seemed to require it. The results that are embodied in Plate I alone of this edition would, had the data for it been collected by a force specially employed for the purpose, have demanded constant occupation from a fleet of ten sail for more than one hundred years. The co-ordinating of these observations after they were made, and the bringing of them to the present condensed form, has involved a vast amount of additional labor. Officers here have been engaged upon the work for many years. This patient labor has been rewarded with the discovery of laws and the development of truths of great value in navigation and very precious to science.
