THE CRYSTAL I'ALACB AND ITS CONTENTS

CORAL ORNAMENTS.—BY PARAVAGNA AND CASELLA.
Red coral has, from time immemorial, boon used as an ornamental material in jewellery, in all
parts of tlie world, in beads, brooches, drops, bracelets, charms, studs, and many fancy contrivances.
The price varies from la. per ok. up to 51. and 20/. per oz. The best colours are considered a blight
red or palo pink : the latter is most scarce. We must not confound with this substance the cord
reefs found by mariners, as they are nothing but a spongy white rock, having no analogy wlintewr
with the real red coral. The fishery of the real coral is carried on in the Mediterranean Sea. Th|
largest samples are taken along the Barbary coast, but not the darkest colours. Along the coast
of Spain a considerable quantity is taken annually, of a deep red colour, but sometimes rather
wormy. The pink and deepest red, but in comparatively small branches, are taken in the Straits
of Bonifacio, between Corsica and Sardinia. The amount annually taken varies from -100,000/. to
200,000/., the principal stations for the fishing smacks being La Torre del Greco, near KoplBSj
Leghorn; and Santa Marghcrita, near Genoa. This article is supposed to give employment to

from 10,000 to 20,000 hands. Thospeei-
mens which we ougravo in our prwait
sheet are from the establishment of Jksrs,
Paravagna and Casella, at Genoa, who em-
ploy 400 workmen. The principal objes
is a superb, and for its size almost WHOM
branch of rough coral in its natural state.

EXPANDING CIKCULAE TAHI.K.

Tins is an extremelv ingenious mo-
tion (patented), which lias received W
honour of a prizo medal. It is a circulor
table, which, by means of a very sun)
arrangement of radiating curved irou^
beneath the top, may be made, by » «S?
revolution of the surface, to expand w
the size required at any moment, ««»
leaves being provided for insertion ■
tween the separated parts. The f*
exhibited is capable of being amt^'a ■,
two different sizes, besides the oBS"™:
form; but, of course, the number *
changes is optional. The mecha:u<m is
simple, that one pair of bauds ran aui; ■
it in a couple of minutes, and that W?
rently with very little excrtiou. ,.,
stand is carved in the Italian style,
grotesque masques.
