Page 245 - This is a most generally useful stadia table for rods reading 100 feet to the foot and with angles up to 30°. The values of other measures than those given in the table are obtained by multiplying the quantities under the proper vertical angle by stadia readings in hundreds of units. The quantity representing the focal distance is very small and is given at the bottom of each page for focal lengths between...

Page 17 - ADD to the tabular quantities four minutes for every degree of longitude the place is west of the standard meridian, and SUBTRACT when the place is east of the standard meridian.
Page 19 - The approximate local time will in general be known with sufficient accuracy from standard time and the approximate longitude of the place. The following example explains the use of the tables and the derivation of the hour angle of Polaris: Position, latitude 36° 20
