entrance to the first " Grand Chamhtr," eighty feet in length, 

 twenty-one feet across and nine feet in height thoughout. At the 

 posterior part of this chamber, in an oblique direction to the left, 

 is an opening five feet in height, forming the entrance to the third 

 chamber, which is about eighteen feet in diameter and five feet 

 high. The floor, however, is covered with calcareous breccia to a 

 depth of thi'ee feet or more. Looking outwards, two openings are 

 to be seen to the left of the first chamber, one anterior, broad and 

 elevated, and one posterior, contracted and shallow, passing 

 obliquely upwards and backwards, a distance of fully twenty-five 

 feet. This chamber is entirely encrusted with carbonate of lime 

 of a cheesy consistence, and in the centre, a perfectly white 

 column reaches from the floor to the ceiling, about six inches in 

 diameter, formed by the union of a stalactite and stalagmite. The 

 antero-lateral chamber passes in an oblique direction upwards, a 

 distance of thirty feet, at which point the ceiling is fully fifty feet 

 high, of a gothic shape, and beautifully ornanie'ited with stalac- 

 tites and fringe like encrustations of carbonate of lime. About 

 sixty feet from the mouth of the cave to the right, is a narrow 

 passage, rough, uneven, and forming the entrance to a chamber 

 the floor of which ascends obliquely upwards a distance of thirty 

 feet, the height of this point being about fifty feet. On the way 

 up a beautiful arch is to be seen, above and beneath which this 

 chamber communicates with the one entered by the antero-lateral 

 opening from the " Grand Chamher," and the light reflected 

 from a lamp through the opening below this arch illuminates the 

 entire ceiling of the adjoining chamber and presents a rich 

 appearance as seen through the opening above the arch. To the 

 right of the oblique floor of the antero-lateral cavity, is an opening 

 horse-shoe shaped, scalloped, about five feet in diameter, and con- 

 siderably obscured by the over-hanging rock. From the body of 

 the cave, the passage leading from this opeoing takes a direction 

 at an angle of about 25° t« the right. Its entii-e length is about 

 270 feet, height between four and five feet, and width the same. 

 The floor is rough and covered with small fragments of rock of 

 vj'rious sizes and from the ceiling hang many small stalactites. 

 At the inner terminus of this passage is an opening more or less 

 circ ular, about twenty feet in diameter, and the rock over it is 

 concave, and fully fifteen feet in height. Stones thrown into this 

 well or cavity give rise to a loud rumbling noise. Its depth is 

 thirty. seven feet, and the bottom measured nine feet by thirty
