wood provided with a handle, the coils may be removed or replaced 
very coveniently.

wheel; G,H,I, being a piece of 
copper twelve inches in diameter, 
the circular ring between G, H, 
I, and a, a, a, isamalgamated, al- 
so the ring K, L, near the centre 
of the plate on the same side with 
the first rg; the wheel is mount- 
ed upon an axis C, D, and turned 
- by a winch. KL, and G, are 
plates of copper, to apply the one 
at the amalgamated ring around 
the axis, the other at the ring at 
the circumference and between 
the poles, N and S, of a horse- 
shoe magnet. G, P, and C, R, are the wires soldered. to these 
plates, their extremities “sont eeter with the g galvanometer ; as described 
above, their length adjusted upon the same principles. 
In experimenting with Faraday’s wheel, the disk K, L, at the cen- 
tre was pressed constantly against the wheel by fastening a cork be- 
tween the disk and the support. The piece of copper G was touch- 
ed to the wheel at intervals so as to assist the vibrations or to destroy 
them at pleasure. When the whee! was first amalgamated, a deflec- 
tion in the needle was produced without the aid of the magnet; af- 
terwards no such deflection was observed. _ Opposite rotations of the 
wheel produce opposite effects in deflecting the needle of the galva- 
nometer, other parts remaining the same.

_ The State of N. York, with more than 2,000,000 of people, is 
happily, very attentive to the great interests of education. It has 
four Colleges; Columbia College in the city of N. York, from which 
there are no returns since 1829; Hamilton College at Clinton, with
