Side 446 - Narrative of the Origin and Formation of the International Association for obtaining a Uniform Decimal System of Measures, Weights, and Coins.
Side 100 - The last decade of the eighteenth and the first decade of the nineteenth century is a momentous period in the history of the roads in London and its environs.
Side 394 - Warden of the Standards on the proceedings and business of the standard weights and measures department of the Board of Trade.
Side 177 - Majesty to inquire into the subject of weights and measures, that a cubic inch of distilled water weighed in air by brass weights at the temperature of 62 degrees of Fahrenheit's thermometer, the barometer being at 30 inches, is equal to 252 grains, and 456 thousandth parts of a grain...
Side 398 - A committee having been appointed to inquire into the original standards of weights and measures in the kingdom of England, to consider the laws relating thereto, and to report their observations thereupon, together with their opinion of the most effectual means for ascertaining and enforcing uniform and certain standards of weights and measures...

Side 116 - A comparison of these two equations show that O' must coincide with S. Hence the center of suspension and the center of oscillation are interchangeable and the distance between them is the length of the equivalent simple pendulum. This is the principle of Kater's pendulum. 121. Energy Changes. The resultant force of gravity acts at C. hence the potential energy of the pendulum in any position is the same as if its mass were concentrated at C. But the pendulum does not swing as if it were concentrated...
