4 It is a lonely place, and at the side 
Rises a mountain rock in rugged pride ; 
And in that rock are shapes of shells, and 
[forms 
Of creatures in old worlds, and nameless 
[worms — 
Whole generations lived and died, ere man, 
A worm of other class, to crawl began."

Earth Currents. 
The action of the currents of electricity 
that pass round the earth may be convenient- 
ly exhibited to a large audience by the follow- 
ing arrangement, devised by Professor W. 
Le Roy Broun: A regtangular frame of light 
poplar wood is suspended horizontally by 
wires attached to the frame of a hydrostatic 
balance, its longer sides in the magnetic east 
and west line, and at right angles with the 
beam of the balance. About the perimeter 
of the frame are previously wrapped a num- 
ber of coils of insulated copper wire, each 
extremity of the wire being made to termin- 
ate near the center of one of the shorter 
sides ; it is there passed through the wood, 
fastened, and cut off about 3 centimeters 
from the frame. The index of the balance 
being brought to zero point, the ends of the 
short terminal wires are immersed in two 
mercury cups for electrical connection. When 
the battery current is sent round the rec- 
tangle from east to west on the northern 
side, and from west to east on the southern, 
the northern side is attracted and the south- 
ern is repelled, and the corresponding defec- 
tion of the balance renders this plainly visi- 
ble. When the current is reversed, the 
deflection is in the opposite direction. By 
breaking and closing the circuit at proper 
intervals, to augment the oscillations, Pro- 
fessor Brown easily made the large frame os- 
cillate through an arc of 5°. When the sides 
of the rectangle were placed N. E. and S. W. 
the current produced no sensible effect.—
