A yellowish resin found in thin layers in the Cretaceous lignite of 

 New Mexico ; it seems to have the formula C.HgO. Soluble in ether, 

 less so in bisulx^hide of carbon ; dissolved by potash, it is precipitated 

 again by acids. Melts at 154° Cent. E. B. T.

A mineral from Loadhills^ reputed to bo aurtchalcite, was found to 

 resemble Caledonite, with which it also appeared to agree in crystallo- 

 graphic characters. Its analysis led to the following rational formula: 

 5PbSO, + 2PbH^O,4.3CiiH,0^. As this composition differs from that 

 assigned to Caledonite, an undoubted specimen of this mineral was 

 analyzed ; its analysis agreed substantially with that of the doubtful 

 mineral. It appears, therefore, that Caledonite is not, as originally 

 represented, a cupreous sulphato-carbonate of lead. 



An analysis of a specimen of Lanarkite gave results represented by 

 the formula PbSO^-fPbO. It contained neither water nor carbonic 

 acid as an essential constituent. F. W. It.
