weigh for Pulo Panjong, and did not return until the 7th 

 of December, having touched at Nattal. On the 8th, Mr, 

 Robinson and the sub-conductor landed with a part of the 

 baggage ; and by the 9th, in the evening, all the articles were 

 on shore, and the tents up. On the 10th, Captain Crisp 

 came on shore ; they observed for the latitude, and found the 

 south-east point of the island nearly five minutes north of the 

 Equator. On the 11th, Captain Crisp sailed for Pulo Panjong, 

 leaving directions for Mr. Lawrence and the conductor to proceed 

 to a small island to the south-east, and to examine if it was suited 

 to the purpose we required.=^ Early on the 16th, Mr. Lawrence 

 proceeded to the island, with the requisite instruments, and a bag- 

 gage-tent, also three Lascars, and landed about three o'clock 

 in the afternoon. The conductor having been sick was not able 

 to accompany the party. On the 17th, they examined the 

 island, found it 11 feet above the level of the sea, composed of 

 sand seated upon a foundation of coral, in length 365 feet, and 

 breadth 200 feet, distant from the main land about 10 leagues, 

 with a good landing-place, and suitable in every respect for 

 making the experiments upon; having dug a hole to the depth 

 of seven feet, they found very good water, and in abundance—" 

 there being no other islands in the vicinity nearer to the Equator 

 than this. On the 18th, Mr. Lawrence returned off Pulo 

 Pinnee, and on the following day, Mr. Robinson proceeded, with 

 a part of the baggage, for the small island, which is called 

 Gaunsah Lout, where he landed ; Mr. Lawrence and the com- 

 mander of the brig sailing at the same time in a smaller boat, 

 which, having been found too deeply laden, and bad weather 

 coming on, they returned, and did not reach the small island 

 until the following day. The instruments and baggage were 

 got to the island by the 7th of January, and the Observatory 

 was put up.

On the Consolidation of the Strata of the Earth. By Sir James 

 Hall, Bart. F.R.S. Lond. and Edin.f 



The public attention, animated by scientific controversy, has 

 of late years been much directed to Geological subjects ; and 



* It appears from a letter of Captain Crisp's, which was despatched by a circuitous 

 route, and which I did not receive until the end of last September, [1823] although 

 written many months before, that,' at this time, his health had suffered very materially 

 by the labour and exposure attendant upon going about, and in an open boat, in search 

 of a proper station for making the experiments upon ; some of his family were alsQ 

 ill at the time at Nattal.
