120 SINGULAR VITREOUS FORMATION. 



and all the recorded experience of discovery, alike 

 warranted us in anticipating. The point upon 

 which r stood was a steep and cliffy rock facing the 

 sea, connected with the main land by a low and 

 narrow neck of land, but almost insulated at high 

 water during the spring tides. A singular cliff, 

 projecting on its S.E. side, is called by Captain 

 King, Carlisle Head ; but we searched in vain for 

 the fresh water, which that distinguished navigator 

 speaks of, as having been found there by him in 

 1819. We remarked here, certain vitreous forma- 

 tions, in all, except form, identical with those already 

 described as having been seen at Point Swan. 

 These were small balls lying loose on the sandy 

 beach, at the bottom of the cliff ; they were highly 

 glazed upon the surface, hollow inside, and varying 

 in size from a musket, to a tennis ball.* 



February 23. — We weighed early in the morning, 

 and rounded Point Cunningham ; anchoring again 

 at 10 o'clock, A.M., 8 miles north of it, in 7 fathoms 

 (low water) ; W. by N., one mile from where we lay, 

 a red cliffy head, called by Captain King, in memory 

 of the difficulties which ultimately compelled him to 

 leave this interesting coast. Foul Point, marks the 

 limit of his survey of this part of the northern shore 

 of Australia, and terminates the range of cliffs,'|"
