RAYGILL FISSURE.

to (3), but towards the bottom there is in front a large mass of 
yellow clay, with large angular blocks of limestone. The space 
between this clay and the southern wall is filled with bone earth. 
At a depth of 3 or 4 feet below the first level of the fissure, or 
31 feet from the top of the opening, there was found the broken 
pieces of the large tusk of an Elephant. There is a large portion 
of the tusk missing, and though every effort was made to secure 
the remaing portions, they could not be found. Along with the 
tusk were numerous other bones of the Elephant, — mostly broken 
and fragmentary as usual ; there were also several large Molars 
of this species. There were also bones, well preserved teeth, and 
broken pieces of tusks of Hippopotamus. The teeth of the Hyena 
were numerous, and in most instances seemed to be those of adult 
or aged animals, the points being much worn. Several ex- 
amples of Rhinoceros leptorhinus, and the broken horn of a 
Roebuck (Cervus Capreolus) were found in the upper part of 
the Cave. Except the teeth, which are generally in a good state 
of preservation, the remaining bones were nearly all fragmentary, 
and so embedded in the hard-cemented matrix, that it is almost 
impossible to ascertain to what animal they belonged. 
Below the vertical depth of 27 feet the fissure branches in 
two directions. One proceeds eastwards, and is nearly horizontal ; 
it is sufficient^ open for a man to be able to creep a distance 
of 26 feet, when a mass of fallen limestone prevents further 
progress ; but beyond this point he could see a further dis- 
tance of about 12 or 14 feet. The second branch lies in a 
souther^ direction and appears to fall rapidly ; the roof descends 
and it is quite filled up at a distance of three or four 3 T ards. 
Where the roof and the sides are exposed they shew evidences of 
abrasion by running water, the surfaces are smoothened and the 
corners of the limestone rounded off. There is little evidence 
of stalagmite having been formed. The uppermost layer in the 
eastern branch consists of similar laminated clay to that which 
was found uppermost in the part of the Cave which has been 
worked.
