[[margin]] p 140 [[/margin]]
Inspected this morning the lead wire which I placed in a perpendicular position on the 10th of Jany, see p 140, with its lower end in a cup of mercury. I found that the process of elevation had apparently been going on continually, and that the mercury had reached the elevation of 14 inches above the surface of the liquid metal in the cup. The elapsed time being 42 days, the elevation has been at the rate of exactly 1/3 of an inch per day on the average, and this is very nearly the same rate with which the elevation commenced. 

I also found that the lead syphon which had previously been used for the transmission of the mercury, still continued to transmit it, but the progress was excedingly slow. While all the mercury was drawn out of the cup with new wire in the course of a few days, but a small quantity has passed up to this time through the other syphon. I think it probable that the suggestion I have thrown out at page 141 is true, namely that a permanent and stable compound is formed after a time between the lead and the mercury. 

Mr Eckfelt of the Mint has promised to make some experiments for me to determine whether gold in a deep crucible which has been suffered to cool gradually, will be found to contain the same amount of alloy at the top and bottom.

Repeated the experiments given at Page 202 with the long wire around the room,_The only difference in the arrangement was that ^[[end]] of the wire which communicated with the out side of the jar did not come in contact with it by a distance of about half an inch, inorder after the manner of Priestly to neutralize the, or I should say, equalize, the electricity of the two sides. 
[[margin]]Exp 1.[[/margin]]
In the first experiment, quite a bright and large spark passed to the knob of the small test jar, which however did not affect the electrometer, It was one of the oscillating sparks.

In the second experiment, the wire inorder to render it steady, was placed over an insulated conductor, and the test jar brough nearly in contact with this. With this arrangement, quite, a large spark passed to the knob of the small jar, which electrified the electrometer quite sensibly, say 10 degrees and more, with a [[underline]]minus[[/underline]] charge. 
[[margin]]Exp. 3.[[/margin]]
Next the conductor [[underline]]a[[/underline was placed in contact with the plus end of the long wire, and the same experiment repeated, the spark was again large and now was found to be [[underline]]plus[[/underline]].
[[margin]]Exp. 4[[/margin]]
Again placed the test jar at [[underline]]a[[/underline]] page 202 the middle of the wire, but could not perceive the slightest spark, although the experiment was repeated three times in succession.
