To quickly assess the difficulty of the text, read a short excerpt:
About this date then, in all probability, the needle in London pointed farthest to the east of north, and it then began to move towards the west. Very slowly, year by year, this westerly movement went on. In 1657, as we have seen, the needle pointed to the true north, but the westerly movement of the needle still continued. It went on until the year 1818, when the needle pointed 24 38' 25" to the west of north. The movement of the needle was then reversed, and since 1818 it has con- tinuously m...oved towards the east, the westerly deflection of the needle having been reduced by 1909 to somewhat rather less than sixteen degrees. We see then that the needle very probably was in its extreme easterly position in or about the year 1578, a position in which its direction would have been about 11 20' to the east of north, and we know that in 1818 the needle was in its extreme westerly position, its direction being 24 38' 25" to the west of north. This would make the period occupied by the needle, in moving from one extreme to the other, about 240 years, and the arc covered by the movement about 36 degrees.
