ROYAL INSTITUTION.

An interesting and very animated lecture was
delivered at the Royal Institution on Friday even-
ing by Mr. F. Buckland, " On the Culture of Fish,"
on which occasion the Duke of Northumberland
was in the chair. Mr. Buckland very enthusiasti-
cally urged the importance of the subject of pisci-
culture, which, he contended, deserves to be con-
sidered as a science rather than as an art ; and he
entered into the matter so thoroughly con more,
and used so much action and freedom of expression,
that he carried his audience completely along with
him, and they seemed to be highly amused as well
as interested. Fish are among the most prolific of
living creatures, the number of eggs that each one
contains being so great that if they were all to be
developed, the rivers and the sea would soon swarm
with them. In a turbot weighing eight pounds
upwards 485,000 eggs have been counted, each one
of which, as Mr. Buckland said, if properly taken.
care of, would become a turbot that now sells for
10s. Such a fish would, therefore, be more profit-
able than the mythical goose that laid golden eggs,
and the practical advantages of attending to the
culture of fish was plainly manifest. He described
the manner in which salmon and trout, especially,
deposit their eggs in the beds of rivers, and the
many dangers the spawn usually encounter, which
so far diminish the number that it is estimated that
not more than one egg in a thousand becomes a
matured fish. It is a mistaken notion to suppose
that the birds that skim along the surface of
rivers are destructive to fish—they only
eat the insects that would destroy the spawn,
and are therefore useful ; but the most destructive
aquatic poacher is the swan, which dives its long
neck to the bottom and shovels up hundreds of the
rggs in its broad beak. The plan to bo adopted in
the culture of the fish is very simple, and the ap-
paratus required may be easily provided. The spawn
is collected and transferred to boxes containing
gravel that has been boiled, to kill the insects it con-
tains, and through the boxes a stream of water not
deeper than 11-in. is kept constantly flowing, at a
temperature of about 40 or 45 degrees. All that is
then required is the practice of the sometimes very
difficult act, as Mr. Buckland observed, of letting
things alone for about 35 days, when the little fish
will come out of the eggs. In that first stage of
development they have no mouths, but each one is
provided by nature with a bag attached to the gills
which supplies it with nutriment until further ad-
vanced in growth. With the aid of the electric
lamp several eggs were exhibited just before they
were hatched, with the fish visible inside and mov-
ing about; and the embryo fish, on first bursting
from the eggs, with their bags of nutriment at-
tached, were also exhibited swimming in water.
Though they bad no mouths they were provided
with large eyes, and their hearts could be seen
beating rapidly, When further developed they are
placed in ponds and fed. In England the food
given them is liver ground very fine, but in France
they are characteristically fed with frogs. When
sufficiently advanced to provide their own food the
fish are introduced into the rivers to take care of
themselves, and to repay when afterwards caught
for the pains bestowed on them in their infancy. In

this manner 40,000 fish, comprising salmon, trout,
greylings, and chad, were put into the Thames last
year ; and as the cost of rearing them is not much
more than a farthing each, if only a small propor-
tion grow up and come back to be caught, they will
repay the expense. In France the rivers have been
stocked with as many as six millions of fish of
various kinds. One of the problems
ciculturists are now engaged in solving is the in-
troduction of salmon into the rivers of Australia;

sagacious as to know the name of every maker
of tackle that is used in the Thames. It has been
observed during
the culture of fish that not un-
frequently two fish are contained in a single
egg, and they are joined together near the
middle, like the Siamese
twins. A specimen of
this kind Mr. Buckland had been so fortunate as to
procure alive for exhibition in the lecture room,
each fish being distinct in every part but at the point
of junctien. At the conclusion of the lecture, Mr.
Buckland made a feeling allusion to his father, the
late Dr. Buckland, and there was a burst of ap-
plause unusual with the audience at the Royal
Institution.

In the Italian ParliamentatTnrin it has been
proposed by the Radical members to strike from tbe
Budget the sum of 1,110,000 f., which the State pays towards
the support of the great Italian theatres—La Scala, in
Milan, San Carlo, in Naples, &c. Although the motion
was opposed in the professed interests ogfataiornt ansthdaotulteuvreert,
