be separated by a piece of wood, to which being attached, and the 
wood provided with a handle, the coils may be removed or replaced 
very coveniently. 
Fig. 3. represents Faraday’s 
wheel; G,H,I, being a piece of 
copper twelve inches in diameter, 
the circular ring between G, H, 
I, and a, a, a, is amalgamated, al- 
so the ring K, L, near the centre 
of the plate on the same side with 
the first ring; 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 connected with the galvanometer as described 
above, their length adjusted upon the same principles. 
In experimenting with F'araday’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 wheel 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 iu the city of N. York, from which 
there are no returns since 1829; Hamilton College at Clinton, with
