76 Differences of Meridian at Madras, [No. 97- 



on a small scale, with an astronomer and a few native assistants ; 

 since that time, the establishment has been improved, and valu- 

 able instruments erected, of which most important use has 

 been made by Mr. Taylor, the present astronomer to the 

 Honorable East India Company. 



In Bengal, we have not had any regular astronomical esta- 

 blishment, but many valuable observations have at different 

 times been taken by the officers of the Bengal Army, employed 

 on geographical and other duties, as well as by gentlemen 

 of the civil service, in different parts of the country, for their 

 own satisfaction. 



With regard to the longitude of the Madras Observatory, 

 it was very assiduously investigated for many years, by the late 

 astronomer Mr. Goldingham, as may be seen by the Madras 

 Observatory papers, and others published by him, and in his 

 Memoir laid before the Royal Society, in which he has recorded 

 the observations made of the eclipses of the satellites of Jupiter. 

 Until the year 1817* the meridian of the Observatory was 

 accounted to be 5h. 21m. 14s. East ; but afterwards Mr. Gold- 

 ingham had reason, by correcting his numerous and valuable 

 observations, by the errors of the tables, and from some 

 emersions and immersions of the 1st and 2nd satellites cor- 

 respondent with observations made at Greenwich, to estimate his 

 Observatory to be 5h. 21m. 9s. *4. 



In the 1st. volume of the Madras Observatory Papers, Mr 

 Taylor gives for his meridian,

By transits of moon and stars. . . . 3*77

 numerous transits, compared with those made at the Cambridge 

 Observatory, finds. — By 14 transits of )H h. m. s.
