length of time and the resulting effects upon the fish are 
noted. The proportion of the fish, chiefly Plarce, Dabs, 
and Soles, which have recovered is surprisingly large, as 
will be seen from the particulars given below. ‘The con- 
ditions were sometimes very different in one experiment 
from those in another and yet the results were in nearly all 
cases favourable. The duration of the haul varied from 
30 to 165 minutes, in some cases the fish were allowed to 
lie on deck in the sun for 10 minutes before being 
placed in the tub, while the time they remained in the tub 
varied from 30 to 180 minutes. Ina few exceptional cases 
where there is a very large mortality this can generally be 
assigned to some special cause, such as the fish being taken 
along with a heavy weight of starfish, or with a large 
quantity of rubbish such as may be got in the net at the 
bottom of the Horse Channel or outside the Liverpool Bar. 
We have picked out from the statistics taken on board 
the steamer by Mr. Dawson the following series of cases 
which relate to the three edible fish with which the 
ereatest number of experiments have been made—viz., 
Plaice, Dab, and Sole. Each of these series, and especially 
the Plaice, contains sufficient examples to allow us to 
draw definite conclusions. The other fish experimented 
with are not yet numerous enough to make it worth while 
recording them.
