26 MR. R. D. DARBISHIRE ON GREAT-ORME^S-HEAD 



Thus, at 126 feet, there occurred to me part of the jaw 

 of a pig; at 186 feet, sheep^s teeth and frequent fragments 

 of bone; at 366 feet, the molar of a horse and many 

 fragments of bone. At 315 feet, on the north side of the 

 road, along with Patella and Littorina, were found a 

 cow^s tooth, part of the jaw and other bones and several 

 teeth of a pig, fragments of other bones, bits of charcoal, 

 and two human molars. 



At 365 feet there occurred fragments of bone. The 

 bones have all lost much animal matter. 



Upon the whole it would seem that all these remains 

 are most probably relics of the inhabitation of the Head 

 by birds or men. The shells are all of such kinds as 

 sea-birds often carry ashore for food. I have myself 

 found Hmpets and periwinkles on the sea-birds^ crags, 

 and on the highest sward, all of which had been so 

 transported. 



In Connemara I have often traced shells of the very 

 same kinds on the hillsides, to or from a heap outside 

 a cabin or the site of one, on or under the sward, 

 according to the antiquity of the deposit. 



The bones probably belong to the human period. The 

 shells, lying on the already elevated ledges of the cliffs, 

 or the shells and bones cast abroad outside some cabin, 

 would in the course of years be distributed down the 

 declivity of the hill along with, and in process of time 

 be buried with and under, the superficial detritus. Wind"^ 

 and rain, and chance footsteps of animals or men would 

 assist in scattering such objects. 



If this be a correct explanation of the occurrence of 

 these shells and bones in the clay with angular fragments, 



* The power of wind in exposed places to move even heavy shells ought 

 not to be overlooked. On the sand-flats at Tunara, north of the Spanish 

 lines at Gibraltar, I have watched a Levanter roll along the heavy shells 

 of Pectunculus and Cardium tuberculatum, and even a massive valve of 

 Fanopaa glycimeris.
