Zin 
larger kills them and leaves them for the crabs and shrimps. 
How do I know this? By repeated experiments and re- 
peated disappointments. Salmon, sea perch (bass), grey 
mullet, and similar hard scaled fishes with scales firmly 
attached, can go through a net and can stand some pressure, 
but these members of the cod family are so tender that the 
slightest pressure is fatal. When collecting specimens, I 
always took all I possibly could with hook and line, to pre- 
vent any crushing, and such as we were obliged to obtain 
by trawling were got by making special drags, only keeping 
the net down ten minutes and then lifting it. Even with 
this care, impracticable in fishing for a living, the mortality 
was enormous. ‘The experiments tried on board the steamer 
of putting them in tanks for two or three hours, and because 
they were alive at the end of that time assuming they were . 
uninjured, are useless. So temporarily tenacious of life are 
they that I always took them alive to the Aquarium, but 
considered myself very lucky if five per cent. lived a week. 
The bulk of them were dead next morning, while of hook- 
and-line caught fish I rarely lost five per cent. 
One_ species of cod, the ‘* Power,’ (Gadus Minutus) 
would not stand the handling needful to take them off the 
hook. These are too small a member of the cod family to 
be much used for eating, but they are exceedingly beautiful 
in an aquarium, far more so than any other of the family. 
At last I took a pair of forceps to sea nS me, and lifting
