FISHES AND FISHING. 367

This apparatus is far superior to any I have ever
seen, and can be adapted to most machines for apply-
ing electro-magnetism, or indeed for frictional elec-
tricity in some of its modifications.
There are machines of a powerful character which
give an interrupted current, used at some of our hos-
pitals to overcome the efifect of narcotics.
All general practitioners should have a proper
machine and apparatus for applyingelectro-magnetisw,
particularly those residing near rivers, lakes, or on.
the sea coast. The expense is trifling, and the utility
very great.
I will with pleasure show any professional gentle-
man, or manufacturer of these machines my improve-
ments.

Calhrhynchts Antartica, — Southern Chimeera.
(Elephant Fish.)

This fbsh is a native of the Southern Ocean, where
it generally inhabits the deepest recesses, and seldom
approaches the shore, except during the breeding
season. It is said to swim chiefly by night, and to
prey upon the young of herrings, cod, and other
smaller flshe&: also on various sorts of mollusca and
testacea.
Its general length is from two and a half to four
feet.
Each jaw is furnished with a pair of broad, bony,
laminsB, notched at the margin into a resemblance of
numerous teeth, while in front, both above and be-
low, stand two large semicircular, flattish, cutting
teeth. The upper lip is extended into a lengthened
cartilaginous flap, or appendage, bending downwards
