Hicks — Discovery of a Hycena-denr. 



two conical bone-crushers is broken, and the fragments of bone 

 gliding down upon the unarmed gum have caused inflammation of 

 the periosteum. One of the hysena's last lower molars exhibits the 

 accessory cusp, which is but seldom developed. The remains of the 

 Ehinoceros are most abundant." 



The cavern is situated in a Carboniferous limestone hill, called 

 Coygan, about two miles to the south-west of Laugharne. The 

 entrance is about 250 feet above sea-level, and easily accessible.

The orifice is low and narrow, about four feet by three. From it a 

 low tortuous channel extends inward for about twenty feet ; this is 

 80 low in some parts that it becomes difficult to pass in a creeping 

 position. A moderately lofty chamber is then entered, which again 

 leads to another and larger chamber — the principal or central 

 chamber — about twenty feet wide by twelve in height. It then 

 branches off into two compartments, a northerly, and a westerly 

 one ; the former extends inward for about seventy feet, and the 

 latter about fifty, when both terminate in rather narrow fissures. 

 The entrance channel, the two chambers, and the westerly com- 

 partment, have a very thick flooring of stalagmite, which has 

 not yet been broken through. The northerly compartment, 

 therefore, is the only one which has been searched ; this was 

 covered over but thinly and partially, and hence easily worked.
