Exp 4 Arranged the coiles and helices so as to produce a shock at a distance with the [[strikethrough]]th[[/strikethrough]] tertiary current - distance constantly increased shock continually decreases in intensity - at the distance of about a foot the effect appears to suddenly cease - no effect was observed beyond - In another current shock 18 inches

Exp 5 Repeated the Exp of day before yesterday on the direction of the tertiary found it is an adverse direction so that of the 2nd and primary current
The magnetism was at first very strong where the two spirals were near each other, it gradually decreased and at the distance of about 6 inches [[?]] disappeared.

Exp 6 [[hand-drawn diagram]] Placed compound helix [[strikethrough]]is[[/strikethrough]] (that is first and second) around the end of the large hollow electro magnet The same screening effect was produced but not quite as [[?]] as in the case of the coils

July 25th My attention today was directed to the[[?]] singular case of of capillary attraction a lead tube was soldered at one end to the plate of a galvanic battery and the other which was several inches higher was plunged into a cup of mercury. The metal was seen on the plate of the battery having passed apparently through the tube like water through a syphon

July 26th 1838 Exp 1 [[hand-drawn diagram]] Arranged 4 posts and on these placed a thick wire about 2 feet or 2 1/2 [[^]]high[[/^]] [[strikethrough]][[illegible]][[/strikethrough]] in the form of a parallelogram. Then sent a shock from the battery of 12 jars through the thick wire - a long wire, which was wound several times (5 times) around the posts and [[strikethrough]]the[[/strikethrough]] a magnetizing[[?]] formed of one part of it [[strikethrough]]The shock[[/strikethrough]] [[?]] the lateral action - The  needle was constantly magnetized in an adverse direction to that of the current. - [[strikethrough]]Jos. Aug[[best guess]][[/strikethrough]] [[^below struck text]] [[?]] [[/strikethrough]] the rope of wire [[?]] [[open bracket]] [which was covered] [[close bracket]] [[?]] was constantly elevated. The action still continued until the  rope was at the distance of about 2 1/2 feet from the lower wire; this was the limit of altitude yet tried.

Exp 2  Instead of the rope of many strands a single wire was next placed in its stead - The small magnetizer [[or magnetized?]] helix was used with the same discharge as [[unidentified symbol or notation?]] quantity the needle was magnetized so as to indicate an inverse current to the [[?]] on a current in the same direction as the battery current NB the rope was not removed during the experiments with the single wire and probably its presence had some influence on the result --
  This is a very puzzling result. The magnetizing helices were nearly of the same diameter [[strikethrough]]and[[/strikethrough]] but of the same size of wire -  It was at first thought that the result might be due to the difference in [[?]] of these helices
  The one however was substituted [[?]] for the other with still the same result
