CURIOUS DISPLAY OF THE GALVANIC TROUGH. 8$
the damage she had sustained at sea, put in at Ilfracombe,
in Devonshire. He was committed to Tothill-fields Bride-
well. Godlia is a remarkable good swimmer, and famous
for remaining under water a long time ; he was the person
employed to dive for a quantity of the forged Portuguese
notes that had been sunk in the Thames, near Lambeth,
and who succeeded in recovering them. He is a Maltese
by birth. Gillington, Farrell, and Joseph De Banon, were
confined in the same prison with him at Lisbon, but had
not been tried when he came away.
Curious Display of the Galvanic Trough.
With respect to the property of metals, Mr. Wilkinson
is amply convinced, that gold and zinc, form the most
powerful Galvanic combination. Fie has lately illustrated
these principles ; giving the preference *o the trough, and
proceeding, by experiments, to evince its wonderful
powers. Four troughs, hung on swivels^ each containing
fifty plates, and eight inches in diameter, the weight of
each trough being between two and three cwt. were charged
with a mixture, consisting of one gallon of nitrous acid, to
nineteen gallons of water. These are so arranged, as to
communicate with two brass rods under the lecturer’s
table, which communicate with brass pillars upon the top
of the table. A piece of harpsichord wire, four feet in
length, being rested upon the two pillars, was in an in-
stant red-hot, fused, and fell upon the table in the form of
red-hot balls, which retained their heat for a surprising
length of time. Wires of silver, brass, and copper, were
placed in the same manner, and with similar results. But,
when five or six feet of steel wire was so placed, it did not
fuse, although its whole extent was rendered red-hot, and
remained so long as the contact was preserved. Platina,
a metal known to be indestructible in the most powerful
