IMFRGVED CAST-IRON.—Cast-iron composed of
old and new metal, in certain proportions calculated
to give it great power of resistance, acquires a new degree
of strength by an addition of 2 per cent. of wolfram, or
tungsten. In one of these combinations the increase of the
power of resistance to fracture per square centimetre, was
44 kilogrammes with French wolfram. In another, formed
of one•third of old English cast-iron and two-thirds of old
ordnance, the increase, with German wolfram was 67
kilogrammes per square centimetre. M. Leguen has
recently shown that, subjected to a second fusion, the
cast-iron containing wolfram is still superior to other
cast-iron similarly treated. After this operation, the
difference of resistance in favour of the former was 26 kilogs.
per square :centimetre ; and German wolfram is superior to
French even after a second fusion. A third fusion of the
same castiron having been directly effected in a Wilkinson's
furnace instead of being done in a crucible, as in the pre-
ceding cases, the tenacity of wolframed castiron was again
greater than that of the common sort treated in the same
manner. Hence it may be concluded that the action of
wolfram subsists even when the fusion is effected directly
in a furnace, and remains after several successive fusions.
The wolframed castiron mentioned above, containing frag-
ments of old ordnance, seems to become stronger at every
successive fusion. Another proof of the superiority of wol-
framed cast-iron over the common sort is, that bars made
out of the former do not bend so much as the others under
the action of equal weights, whence it may be inferred that
the wolframed sort is more elastic and more capable of re-
sistance. In all cases, therefore, in which it is required to
have cast-iron offering great resistance to fracture, the ad-
dition of a small quantity of wolfram offers an easy means
of obtaining it. The wolfram must be pulverised, but need
not be reduced. French wolfram must, however, be roasted,
in order to drive off the sulphur and arsenic it contains;
but German, being purer, need only be reduced to powder

ARRIVAL OF GEN. GARIBALDI AT GIBRALTAR.—
The following telegram, announcing the arrival of General
Garibaldi at Gibraltar, was received from the Duke of
Sutherland yesterday. As the Undine left St. Mawes on
Thursday last, the voyage has been effected in five days,
the time anticipated at the time the vessel left England :
" Gibraltar, Tuesday. The yacht Undine arrived here to-
day, and leaves on Wednesday night for Caprera. All well
on board,"
