VUI. Electro-magnetic Experiment. 
M. Nordenskiold of Abo, now in this country, has communicated to 
me the following curious and simple experiment of Dr. Seebeck of 
Berlin. Take a bar of antimony about eight inches long, and half an 
inch square, connect its extremities by twisting a piece of brass wire 
round them so as to form a loop, each end of the bar having several 
coils of the wire. If one of the extremities be heated for a short time, 
with a spirit lamp, electro-magnetic phenomena may be exhibited in 
every part of it.
