EXPLORATION OF TT NEWrDD CAVES, 



129 



[The position of the rhinoceros-tooth is indicated at sect. XI 7, at 

 the end of the compact gravel excavated when the drawin^^; was 

 made. The excavation has since been continued to the same level 

 as far as sect. XVIII, but no other fossils have been discovered. 



The roof beyond sect. XVIII continues at approximately the 

 same slope as between the two openings, and as the ground oatside 

 is more nearly level, we are approaching the surface. The material 

 excavated beyond the last paint shown in the drawing (PI. VIII) 

 is almost pure sand, at least 5 feet thick at a distance of 10 feet 

 from sect. XVIII.]

The various measurements were all taken from the highest point 

 in the roof above each section, and the distance above or below 

 datum refers to this point. Sections XII and XIII were mea- 

 sured from the surface over the second swallow-hole. A few of 

 these measurements are appended (see p. 130), and their position 

 can be found on the plan (fig. 2, p. 124) and longitudinal section 

 (PL VIII).
