exhibited at the meeting of the Geological Society, on the 8th inst., 
some beautiful specimens of a new mineral recently discovered in

Victor von Lang, of the University of Gratz, and formerly of the 
Department of Mineralogy in the British Museum. It consists of a 
basic sulphate of copper, insoluble in water, and is disposed as an 
incrustation upon very soft ‘Killas’ slate in masses of a rich blue

system. It was obtained from Mr. Talling, dealer in minerals,
