Captain Cook's Journal During the First Voyage Round the World Without a tree or a path to guide them, they took an irregular course by observations of the North Star, and the unreliable needle of an azimuth pocket-compass. The old Santa Fe trail The Story of a Great Highway The collimation error was found by reversing the instrument and using a terrestrial mark, the azimuth error by star observations.

The Flying Saucers are Real As the variation in azimuth for each degree of latitude is small, the table is only computed for the even numbered degrees; the intermediate values being readily obtained by interpolation. Scientific American Supplement, No. 360, November 25, 1882 The altitude and azimuths will only be approximate, but the main thing is to see how the shooting stars are situated with reference to the fixed stars.

Born in Exile Or, in other words, an error of one degree in finding one's latitude would only introduce an error in the azimuth of one and a half minutes. Scientific American Supplement, No. 360, November 25, 1882 Here we found the variation to be 14 degrees 28' easterly, per azimuth.
