Sauuarg 



If two flints are attached 

 by a piece of string and 

 struck against each other 

 whilst held suspended in the 

 air, they emit a sweet ringing 

 sound al- 

 most like 

 that of a 

 bell. 



Certain 

 fossil 

 sponges 

 called ven- 

 triculites 

 may also be 

 found 

 amongst 

 chalk debris\ 

 they are 

 usually met 

 with in two 

 pieces, hav- 

 ing snapped 

 asunder at 

 RESONANT FLINT, the narrow- 

 est part ; but 



by putting the upper and 

 lower halves together we 

 may easily imagine how they 

 looked when growing on 

 some sea-shore countless 

 ages ago. 



I pick up flint ventriculites 

 in my garden amongst other
