"It has always seemed that a great need has existed for an Ephemerides covering a period of 200 years, that is, from 1800 to 2000 inclusive . . . The present compilation is the attempt to fulfill that need. With this Ephemerides and a Table of Houses, all the necessary equipment is at hand to enable one to set up an estimate chart for any historical period, significant event, or for any individual's date, within this 200 years."" --the author's Preface."
