are remarkable, when they have attained several 

 inches of length, by their extreme flexibility, while 

 calcareous stalactites are broken with the slightest 

 effort*. In his account of his own cabinet, Trebra 

 mentions that, in 1782, a peasant digging his gar- 

 den in the village of Seppenrode, dependent on 

 the bishopric of Minister, found a grey flint, about 

 nine inches in length by four in breadth, having 

 nothing particular in its exterior appearance ; but 

 having broke it for his tinder-box, he found within 

 a cylindrical cavity, containing twenty little pieces 

 of silver, which appeared to have been tied with a 

 thread, of which some vestiges were apparent. 

 The cavity was exactly moulded on this little pile 

 of coins, and the inside was black ; but the most 

 surprising circumstance is, that the most ancient 

 of these coins are only of the sixteenth century. 

 Trebra's cabinet contained a piece of this flint, 

 and one of the coins presented to him by Prince 

 Gallitzin, with an authentic certificate of the cir- 

 cumstances above-mentionedf. Mr. Kirwan has 

 another example of coins found in flint J.
