4rth. Obser- 

 vations of eclipses of Jupiter's satellites in 

 1825 at Bushey Heath. These amount 

 to 25, and the results are given both in 

 Bushey and Greenwich mean time. 



There was also read a communication from 

 Major J. A. Hodgson of the 61st Bengal 

 Native Infantry, Revenue Surveyor Gene- 

 ral, residing at Futty Ghur on the Ganges. 

 This letter records seventy-five observations 

 of the eclipses of Jupiter's satellites, made 

 at Futty Ghur (latitude 27° 21' 35" N.) 

 in the autumn of 1824s and spring of 1825. 

 Some of these observations were made by 

 Major Hodgson himself, and others under 

 his superintendence, by young men who 

 are his apprentices in the Revenue Survey 

 Department. The names of the several 

 observers are given, — each observation has 

 its appropriate meteorological indications 

 registered, and the natin-es, powers, and 

 qualities of the telescopes employed are 

 respectively described. These observations, 

 compared with corresponding observations 

 of the same phenomena, in places whose 

 longitudes have been accurately ascertained, 

 will serve to determine the longitude of 

 Major Hodgson's observatory.
