119 Jun 4th 1840 [[top margin]] [[?]] storm for several days [[/top margin]]
7 [[left margin]] see exp with [[girddles?]] [[/left margin]] Repeated exp. 5 with the short wire [[clarks?]] galvanometer. When the iron was out, the deflection of the needle at making and breaking contact was about 10 degrees - when the iron was within the helix and around the coil, the deflection was about 3 [[degree symbol]] - this indicates very clearly the screening influence of the iron. The direction of the current with and without the iron was carefully noted, but no difference could be perceived. 
The iron tube therefore, although it evidently in part [[neutralizes?]] the effect, does not invert the direction of the current.

8  [left margin]] see apr. 23 exp 8th [[/left margin]] Next studied this action by putting coil No 4 around a broad ring of thick plate iron, and [[strikethrough]] coil [[/strikethrough]] helix No 1 within, [[image of ring and wires]] This with arrangement the shock was very small on account of the closed circuit and on account of the action of the iron, the induction to affect the galvanometer was also small although very perceptible, causing the needle to move through 2 or 3 degrees. The plate iron of the ring is about 1/10 of an inch thick but the direction of the current as indicated by the clarks galvanometer was the same whether the iron was between or not. This result is in accord with that of the last experiment.
With the long wire galvanometer, the screening influence of the iron was not well marked. [[end page]]

9 [[image]] Placed the cylindrical coil within helix No 2, and between these put a cylinder formed of varnished iron wire. The effect was increased when the iron was removed, or in other words, the presence of the iron on the outside of the coil partially neutralized the shock. The current set in motion in the iron on the outside would be in an opposite diection to that of the coil within, and hence the result. Iron therefore placed between two coils does not act precisely as other metals, since it has a neutralizing influence independent of the conduction of a closed circuit.

10 [[image]] Put the cylindrical coil within helix No 2, and within the former a bundle of magnets formed by magnetizing ^ [[6?]] large flat files. The shock was much increased by the introduction of the files, but no different appeared to be produced by so placing the files that their magnetism would be increased or diminished by the action of the galvanic current around them. Repeated this exp., put the helix at the end of the coil [[image]] so that without iron in, scarcely any shock could be felt, the magnets were then gradually introduced and first one end put in and then the other, but no difference could be perceived in the intensity of the shock. [[?]] this by the galvanometer also by the artificial magnet.
