accuracy-I am far from attaching any particular importance to this trifle, but as an Astronomical table formed upon modern research, it is I believe the first ever constructed by any of my countrymen in this part of the peninsula, and as such will, I hope, meet with your protection and favour. In order to shew the principle and utility of the table I have thought it necessary here to give an example of an occulation and of an eclipse of the sun as follows. On consulting the Nautical Almanac it appears that on the 8th of November 1834 × Capricorni will be occulted by the Moon at some part of the Earth and probably will be visible at Madras at about 2h. 30m. Greenwich mean time; to discover if it will be visible I proceed as follows. h at which moment the angle from the meridian is 210 15m. computing from the Nautical Almanac. The Moon's Mean Correction from the table The Moon's apparent The star's from Nautical Almanac. Difference, Right Ascension. Declination. 0 41, 49 47 48 Secant 0, 026465 10 22 A. R.

From the Nautical Almanac it appears that the above eclipse of the sun will be visible at Madras, and by a rough approximation, with the assistance of the table, I find it will commence at 19d. 23h. 7m. Greenwich Mean Time, or November 20d. 4h. 28m. 9s. Madras Mean Time for this moment the horary angle 70° 12' and Right ascension Declination. h. Now the sum of the semidiameters of the Sun and Moon being 32' 57" it appears that the eclipse has not commenced at 4-h. 28m 9s; if we therefore repeat the computation for 10 minutes later, the distance of the centers of the Sun and Moon is 33' 28" shewing that the eclipse has not yet commenced, and by interpolation it appears that the time of commencement is at 4h. 39m. 5s. Madras Mean Time. Hoping the above will fully explain the utility of the table, I beg to be Your most obedient and humble servant GODAY VENCAT JUGGAROW. * Since writing the above the occultation of a Capricorni has been observed at the Honorable Company's Observatory at 7h. 48m. 4s.
