ny faculty of the
kind, it must be the dullest imaginable. From the horny construction of
the palate, their taste cannot be acute, and their sense of smelling
(judging from the medium by which all odours are conveyed to them,)
must be peculiarly defective. Taking the above suppositions to be
correct, it is of course clearly apparent that they must be guided
solely by the eye in the selection of their food; for instance, when
fish are stupefied or fuddled as it is termed, I do not suppose their
olfactory organs are affected by the berry or drugs, used to intoxicate
or kill them. I am persuaded, that small balls of paste or bread would,
if offered to them at the same time, be devoured at precisely the same
rate as those prepared with unguents or drugs.
The formation of fish is peculiarly adapted to water, through which
they glide with the greatest facility; their motions being regulated by
the fins and tail; the tail indeed being to the fish precisely what a
rudder is to a ship. The air bladder in fish is another wise provision
of nature, by means of it they can remain for a long time under water;
still they must from time to time take in supplies, for if during a
severe frost the ice be not broken on ponds, the fish therein would
perish for want of air. Some fish are much more tenacious of life than
others; Roach, Perch and Tench, have been conveyed alive, for stocking
ponds, thirty miles, packed only in wet leaves or grass. One thing is
quite certain as regards all fish, viz., that they live longer out of
their natural element in cold than in hot weather. A clever invention
for the transport of fish has come under my notice; an account of this
machine may prove interesting to some persons, and therefore I insert
it.
THE TRANSPORT OF TROUT AND GREYLING.
The Apparatus consists of a tin case, separated into two parts by an
open work partition. In one of these the fish are placed, and in the
other is fixed a mechanical contrivance for keeping up a considerable
supply of air in the water.
In November, 1853, 33 Greylings were sent from the Wye at Rowley to the
Clyde at Abington, a distance of about 250 miles with the loss of only
two fish.
The Apparatus is composed of a zinc cylinder, about three feet high and
two feet in diameter, with a strong iron handle running round the
middle; to the top, a small force pump is attached, and by this fresh
air is forced through a star shaped distributor at the bottom of
