Excerpt from Geodesy The once generally accepted ratio 298 299 of the earth's axes may be said to have disappeared finally on the publication (in 1858) of the investigation of the Figure of the Earth in the Account of the Tri angulation of the British Isles, when it was replaced by 293 294. At the same time that this ratio is, in the present volume, still further altered in the same direction, the formerly received value of the ratio as deduced from pendulum observations is now altered from something like 288 289 up to the same figures as now represent meridian measurements, namely, about 292 293.

Thus, the disagreeable hiatus long supposed to exist between the result of actual meridian measure ments and that deduced by Clairaut's Theorem from the actually observed variations of gravity on the surface of the earth, has now disappeared - thanks to the energetic labours of General Walker and his efficient staff of Officers.
