surempnt of the great meridionnl arc, resting upon eight bases, and 

 extending from Cape Comorin, in the parallel of 8o, to the foot of the 

 Himalaya, in 30^ north latitude, a distance of 1320 geographical 

 jniles, has, during the last year, been brought to a close. This arc 

 has been connected by lateral series of triangles with Calcutta, Bom- 

 bay, Madras, and Benares: ttie wliole of the tract south of the river 

 Khiistiiiah, in the parallel of 16o nearly, wiih the exception of Din- 

 diirul and part of Nellore, has been accuraiely surveyed : north of 

 that line, to the borders of Hindustan, only Kandeish and part of the 

 Hydrabad territory are still lo be examined. Many of the maps of 

 this survey, on the scale of 4 inches to a mile, are already published, 

 and the rest are in course of publication. This work does honour to 

 the enlightened views of the East India Company, who instituted it, 

 and to the zeal and energy of iheir officers who have carried it into 

 execution. 



Sind. — Of Sind we have a notice by Captain A. Burnes, who has 

 again recently lefi Bombay on a mission to Cabul ; and we have a 

 good earnest in what he has already done that he will lose no oppor* 

 tunity of acquinng further inforuiation. 



Arabia.~T\\Q shores of the Persian Gulf have been already survey* 

 ed, and, with the excellent charts of the Red Sea just completed by 

 the officers of the East India Company's service, have made us fully 

 acquainted with the east and west coasts of Arabia; from the Straits 

 of Bab el Mandel, to the eastward of Makullah, the southern shore 

 has also been surveyed. Of the interior Lieuttnant Wellsted, of 

 the Indian Navy, has given us some account ;— first, in a journey 

 from ttie south coast to some remarkable ruins, about seventy miles 

 in the interior of the eastern part of Yemen ; secondly, by a 

 very important journey of seven hundred miles in the interior of the 

 province of 'Oman, under the dominion of the Imam of Muskat.* 



Berghaus, also, has publisiied a map of Arabia during the past 

 year. 



^M;)Ar«^e*.— This river has been explored (thanks to the liberality 

 of the British government), and the practicability of its navigation, 

 with proper vessels, from Bir to the Persian Gulf- a distance, includ. 

 ingits windings, of nearly 1000 miles— has been fully demonstrated by
