Jater formations ; the round and isolated hill Gu- 

 nung Angsana, about five miles North from the 

 Gedé, being the only spot, where the volcanic 

 rocks are found in situ. That the sand and 

 other light tufaceous matter, ejected from the 

 crater, liave fallen into water, and by its means 

 been distributed, is proved by the regular strata, 

 in which they are still observed, though no longer 

 in a horizontal position, having been broken up 

 and displaced by their subsequent elevation. Some 

 of the lower beds of these volcanic ashes, resting 

 upon limestone, contain a number of sea shelJs. 

 The limestone itself abounds with similar pro- 

 ductions and again reposes upon more ancient 

 and black, submarine and tufaceous formations; 

 numerous sea shells, as oysters and cockles being 

 plentiful throughout. 



In these lower black strata, near Kampong 

 Munchang, were disco vered two tusks appearing 

 to belong to some animal of the genus Sus, but 

 too fine for any of the swine tribe, now existing 

 in the forests. Unfortunately they were in a very 

 brittle state and almost crumbled in the hand; the 

 enamel was still perfect, showing no marks of 

 abrasion from water ; so that they cannot have 

 travelled far; proving, that at that early period 

 some habitable land existcd in the neighbour- 

 hood, as is further confirmed by the numerous 

 impressions of leaves and carbonized wood, which 

 some strata affbrd. 



The strata of the different tuffs and lime are not 

 conforraable ; that is, the different beds are not
