 Gives an account of the exploration of the cavern. Considers that 

 the flakes in the cavern have been derived from a " trail of drift 

 gravel " scattered over the table-land above, and were washed in with

 due to natural causes. Concludes that " this Cavern furnishes no 

 satisfactory evidence of the existence of Palaeolithic man." W. W.
