2. Stalagmite. 



3. Breccia.

5. Cave-earth. 



6. Shingle.

The cave is about 66 feet above the bottom of the 

 valley V. 



The exploration, as far as it could conveniently be 

 followed, was completed in the summer of 1859, the 

 work having been carried on in galleries, which, with 

 many ramifications, comprised a space measuring 135 

 feet from north to south and 100 from east to west, as 

 reported by Mr. Pengelly. 



In the abstract of the report by Professor Prestwich, 

 published in the ' Proceedings of the Eoyal Society,' 

 vol. xx. 1872, it is stated that ' mammalian remains 

 were found sparingly in the stalagmite, No. 2, in 

 abundance in the cave-earth, No. 5, and rarely in the 

 shingle, No. 6.' They are of the following species : 

 Elephas primigenius (Mammoth), Rhinoceros ticho- 

 rhinus (Woolly Rhinoceros), Equus caballus (common 

 Horse), Bos primigenius^ Bos taurus (common Ox), 

 Cervus elaphus (Red Deer), C. tarandus (Reindeer),
