1836.] Notes on Dehli Point, Pulo-Tinghie, &$c. 577 



Tinghie densely covered with jungle, most difficult to penetrate, with- 

 out more time than our public duties permitted ; hence the specimens 

 are not numerous, and were found along shore, generally from masses 

 lying about. No stratum was seen. The island terminates to the east- 

 ward in a high reddish coloured cliff, but at which we had no oppor- 

 tunity of landing. 



Nine specimens marked Pigeon island, from a moderately high 

 and cliffy islet some miles to the southward of Pulo-Tinghie, obtaining 

 its name from the abundance of a fine cream-coloured pigeon, having 

 the wings and tail tipped with black ; the same bird which is found 

 on the small islands on the Tenasserim coast. No. 25, from a large 

 mass partly beneath the surface of the sea. 21, high cliffs around, 

 as well as No. 22. 



Returning from the eastward, we had an opportunity of examining 

 a group of small islands called Pulo -Romania. These islets, about 

 two miles to the southward of Point Romania on the Malay peninsula, 

 are partially covered with wood, and appear to be formed chiefly of 

 granite of two kinds, which was seen checquered by fissures in all 

 directions, and intersected by Nos. 34 and 35, found standing above 

 the general level in narrow ridges, the granite being more easily 

 disintegrated than the intersections themselves. No. 31 found in 

 layers of various ^thickness, and No. 29 in large irregular masses 

 some 15 feet in length, on shore or partly immersed in the sea. 



Enclosed are thirty specimens, from a remarkable group of islands, 

 lying between Jan Salang, (Junk Ceylon) and Palo-Pinang, parallel to 

 the kingdom of Quedah and in sight of the mainland. Passing over ma- 

 ny islands visited, all of which will be found worthy the attention of the 

 geologist, and the ornithologist, as well as the conchologist, I shall 

 only mention Pulo-Ledah, as one of considerable importance, from 

 the circumstance of pelagic fossil remains being found in the rocks. 



Pulo-Ledah dedarat, literally in the Malay language, ' Tongue island in 

 shore,' to distinguish this from another Pulo-Ledah de laut, or ' Tongue 

 island at sea.' This island is about a mile and a half in circumference, 

 and rises to the height of 4 or 500 feet, crowned by a castellated 

 looking rock with perpendicular strata : the whole appears composed 

 of limestone, having a considerable proportion of siliceous matter 

 deposited in it, with veins of quartz a few inches in breadth occa- 

 sionally intersecting it. The general rock was found stratified from 

 one to three or four feet in thickness, lying at an angle about 45° 

 dipping to the eastward ; all the surface, wherever exposed, is rough 

 and uneven, of which Nos. 15 and 24 are specimens. Numerous caverns 

 were found whose roofs not being so exposed were more smooth,
