Extract

The author states that the results of the Trigonometrical Survey of Great Britain are nownearly ready for publication, and that he has deduced from them the most probable measures which they afford of the length of a meridian, and the figure of the earth.

After determining the most probable spheroid from all the astronomical and geodetical operations in Great Britain, it has been found that the plumb-line is sensibly deflected at several of the trigonometrical stations; but in almost every case the physical cause of such irregularity may be with probability inferred.
