It was found lately in the trap rock which exists in the neighbour- 

 hood of the town of Galway, and which also abounds in epidote, 

 and some other rare minerals. ,-. .■ ■ '^ ' 



The single specimen which I have! examined is amorjihously iffl* 

 bedded in the trap, and is easily recognized as gadolinite by its 

 black colour, peculiar lustre and fracture, hardness nearly equal to 

 that of rock crystal, infusibility before the blowpipe (intumescing, 

 however, into cauliflower-like masses), and its gelatinizing with 

 muriatic acid. ■jJIj; hj^h)" '■ : -I remain. Sir, Yours, &c.,
