OPERATIONS IN THE PENINSULA. 36\9 ] 1. Latitude and longitude ofKylasghur, Let Y be Yerracondah, K Kylasghur, and P the pole.

If the same angle be brought out by using the co-latitudes of Yerracondah and Kylasghur, and the observed angle at Yerracondah, between the N. pole and Kylasghur, it will be 87° 35' 37", very nearly the same as was observed. Then again, as the sine of either of the co-latitudes, is to the sine of the opposite angle, so is the sine of the oblique arcKY, to sine of the angle KPY, equal Bb.
