2. The same results were obtained from rails laid all around the
northeast curve, and even after they had acquired a due west to east
course; showing that each rail acquired the same magnetic polarity which
would be exhibited by any magnetic needle oscillating freely in our
northern hemisphere, dipping also at its north end considerably downward
if suspended at its center of gravity.
3. Applying the needle at the _west_ terminus, a few anomalies were
observed; but, especially nearer the junction, the rails all gave the
normal result found on the main track.
4. The wheels of the cars standing on the north and south track followed
the same law, exhibiting both vertical and lateral induction, so that
the lower rims and the forward or north part of the periphery attracted
the unmarked end of the needle, while the upper and rear, or south
portions of the periphery of the wheel attracted the marked end.
5. The wheels of cars standing on the east and west road exhibited
the following modification.
