■Coniputation of the eclipse of the sun for November 

 19th 20th 1835. 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

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. 2%m 9-5 ; 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 com- 

 menced, and by interpolation it appears that the time of 

 commencement is at 4h. 39m. 53. Madras Mean Timie. 

 Hoping the above will fully explain the utility of the table, 



I beg to be
