Side 5 - June 1819, they give their opinion, that " there is no practical advantage in having a quantity commensurable to any original quantity, existing, or which may be imagined to exist, in nature, except as affording some little encouragement to its common adoption by ueighbouring nations.
Side 32 - ... is less than that in the parallel of 9° 34', a degree and a half farther to the south. This is similar to what appears in the degree in England ; and there is an instance of the same species of retrogradation, when the parts of the arch between Dunkirk and Formentera are compared with one another. Some part of this irregularity, but certainly a very small one, may be ascribed to error of observation ; the greatest part must, we think, be placed to account of the irregularities in the direction...
