In the Problem of the Figure of the Earth the ellipse is a convenient curve of comparison for this further reason that it was the exact form of each meridian when the earth was fluid or sufficiently fluid to control the external figure. [...] The real importance of knowing the exact form of Indian arcs is seen in the effect which an erroneous determination of the curature may have upon that accuracy in the Mapping of the Country which the Great Survey is supposed to ensure. [...] For computing the amplitude of an elliptic arc it is necessary to know (1) the length of the arc (2) the lati-185S.) and the Figure of the _Earth. [...] Then in the determination of the amplitude by observation all the elaborate instrumental observtions and calculations of the latitudes of the three stations at the extremities and the middle of tho arc in question (viz. [...] Hence the difference between any two successive sines is not the nadlika.Bhogya-khantfa ; but if the arc instead of being deflected be increased in the direction of the tangent then the increase which would take place in the sine is the Taiktilika Bhogya-khantia i. c. the instataneous ration of the sine.
