Page 31 - Vertical circles are those which pass through the poles of the horizon, (the zenith and nadir,) perpendicular to it. The meridian is that vertical circle which passes through the north and south points. The prime vertical is that vertical circle which passes through the east and west points. The altitude of a body is its elevation above the horizon, measured on a vertical circle. The azimuth of a body is its distance, measured on the horizon, from the meridian to a vertical circle passing through...
