Describes the liquid obtained from the cavities of a specimen of 

 enhydros^ or "water-stone." It consists of clear water containing 

 in solution a smaU i)roportion of certain salts, apparently the chlorides 

 and sulphates of sodium, magnesium, and calcium. He believes that 

 a soluble form of silica is also present. The. accompanying plates 

 show the crystalline forms of the saline constituents obtained on eva- 

 poration, and the crystalline structure of lamince forming the waUs of 

 one of the enhydros. The probable origin of these water-stones and 

 their bearing upon the formation of mineral-veins are discussed.

A large mass of nearly pure arborescent metallic copper was picked 

 up on tlie banks of the Yarra-Yarra river, at Footscray, amongst loose 

 fragments of weathered " bluestone " or basalt, of which the banks of
