phorus and vanadium — the members of which have a numljer 3f 

 properties in common, and isomorphously replace one another in 

 the mineral kingdom. Further work is necessary for the eluci- 

 dation of this matter, which is beyond the scope of the present 

 note. 



A mixed sample of undecomposed blendiferous limestone of 

 Broken Hill was carefully tested by Mr. J. B. Bull for the 

 presence of vanadium; the concentrate of the limestone was also 

 separately tested, but no vanadium was found, neither were 

 vanadium minerals detected on examining microscopically the 

 blende-bearing limestone ; but it must be remembered that only 

 a comparatively small amount of the sulphide limestone has been 

 opened up. Further work may reveal the presence of vanadium 

 in the unoxidized zone ; meanwhile the author puts forward the 

 suggestion that the origin of the vanadium is in some way closely 

 connected with the presence of the phosphorus of the bones.
