FISH KEPT ALIVE OUT OF WATER
ellis Kept Moist and Oxygen Fed
Them In Their Boxes.

Translation Made for the Literary Digest.
Fish alive and kicking may now be re-
| ceived at any distance from the waters in
| which they are captured. In other words,
| the salmon of the Columbia, the trout of
Maine, the bass of Florida may be shipped
| to any part of the United States with as
great facility as bale of hay or a crate
| OF oranges. And when the fish reach their
destination they are as lively as II they
were in their native element although they
have not seen the water since they were
| taken from sea or river. The possibility
| Of doing this we owe to the Germans, and
| in a recent issue Of Der Tag (Berlin) Hans
Dominik tells us how 1t may be done. Mr..
Dominik says:
"a short time ago I went to the labo-
ratory Of DR.. Eugene Erlwein, and this
gentleman showed me large glass case
case: on the shelves saw a large number
| OF Ash OF every variety. There were fat
carp and pike, trout and bass and other
watery denizens. end they were an well
exactly as II they were in the water. al
| though they had not felt this element for
thirty hours The manner IN which this
| was accomplished was soon explained to
me-"
| Mr.. Dominik says that the floor of the
| case was covered with q thick layer OF
ceptacle moist and the giils Of the fish in
consequence never became dry. But fur

| beside the case there was a large steel CYL

| the cylinder to the base of jar filed with
water, and another tube led from the neck
| of the jar into the box containing the fish.
| Says the writer:
LAS 1 watched the apparatus I saw the
oxygen bubble through the water of the
jar and then. after being saturated with
| moisture. pass into the case. But the oxy
| gen in the case was not stagnant; there
was a pipe at one end which allowed the
excess oxygen to escape. 1t was now clear
| to me how the fish could be kept alive and
happy without water-the oxygen passed
through their wet gills and into their blood
in exactly the same way as II they were

mouths, and when the gas began to bubble

Mr.. Dominik says that in these expert
ments the case contained three hundred
weight Of fish, while the case itself only
weighed one NEUTRALITY-SUSPICIOUS. there was
only one-fourth dead weight. Dr. Erlwein
has, however. carried his experiments fur
Their along this line, and he has now pat
ented a special fish car for use on railroads:
in this car the above principle is used. but
with slight notifications. Thus the fish
are placed in little water in the car, and
the water Is kept in constant circulation by
| means Of small pumps. As. 1t circulates
the water passes through an apparatus
which extracts the carbonic acid and in
jects into the fluid pure oxygen. The fish
