A technical manual of geodetic astronomy for land surveyors, written by Theodore Graham Gribble and published by J. D. Potter in London in 1921. The plates are dense engraved graphs on fine grid rules, with fans of curves for hour angle, azimuth and declination, hand-lettered axis labels and single-letter curve keys usable as ready-made scientific diagram texture.
