manganese. A sulphurinate of manganese is thus formed in the 
oxide, from which it is separated by throwing the whole into 
water, which dissolves the sulphurinate. Caustic barytes preci- 
pitates the manganese, and forms with the sulphurin a salt very 
soluble, which crystallizes like nitrate on muriate of barytes. 
The sulphurinate of barytes thus obtained is decomposable by 
sulphuric acid, added gradually to its solution, which precipitates 
the barytes, leaving the sulphurin acid in the water. It may be 
much concentrated without any loss. 
VESTIUM, A NEW METAL. 
This metal has its name from the discoverer, Professor Von 
Vest of the Johanneum in Gratz. It is found in the nickel ore 
of Schladming (an ore mixed with cobalt pyrites) ; and also in 
cobalt ore. In its reguline state it has the appearance of iron, is 
brittle, and has a fine granular texture. The existence of this 
metal is, however, questioned by Mr. Faraday and Dr. Wollaston. 
CRYSTALLIZED DIAMOND IN IRELAND. 
An exceedingly fine specimen of crystallized diamond has been 
found in the sand of a small stream in the north of Ireland. It 
is of the species called by lapidaries the yellow diamond, of ex- 
treme beauty and remarkable size.— Public Journals. 
THE NECKONITE (A SUPPOSED NEW MINERAL). 
[Extract of a Letter from Dr. H. H. Hayven of Baltimore, to Professor 
Stturman of Yale College, United States. | 
‘¢ Tt (the necronite) occurs in a primitive marble or limestone 
which is obtained twenty-one miles from Baltimore. It occurs 
for the most part in isolated masses in the blocks or slabs both 
in an amorphous and crystallized state. It is most commonly 
associated with a beautiful brown mica of the colour of titanium, 
small but regular crystals of sulphuret of iron, tremolite,and small 
prismatic eircles of titanium which are rare. The form of the 
crystals is a rhomboid avproximating very much to that of the 
felspar, and which has inclined some to consider it as such. Also 
the hexaedral prism resembling that of the beryl. This form is 
rare, and has uot as yet, | believe, been found complete. Its co- 
lour is a blueish white and clear white. Its structure much re- 
sembles felspar ; being lamellar, sometimes opaque, semitranspa- 
rent and transparent, at least in moderately thin pieces. It 
scratches glass, carbonate of lime, and even felspar in a slight 
degree. In all our efforts it has been found infusible per se, or 
with borate of soda, and even from all the force of heat that could 
be excited in a smith’s furnace it came out unchanged in every 
respect. The acids seem to have no sensible effect upon it, either
