Page 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.

Page 9 - ... but few examples. It was not long after the commencement of this survey, that a system of trigonometrical and astronomical operations of still greater extent was undertaken by the French government. The want of system in the weights and measures of every country ; the perplexity which that occasions ; the ambiguous language it forces us to speak ; the useless labour to which it subjects us, and the endless frauds which it conceals, have been long the disgrace of civilized nations.
