THE author has embraced the opportunity afforded by a second edition of this work to introduce into it certain changes which, without modifying the general plan and scope, will, it is hoped, increase its usefulness. For the most part these changes are made in the direction of increased simplicity or of increased precision, and are most conspicuously shown in 19, 23, 3,2, 37 and 38. The tables at the end of the book have been considerably increased, both in extent and precision, and now suffice for approximate as well as rough determinations of time, latitude and azimuth without the use of an almanac.
