Proposal for a new "Regulation of Weights and Measures. 115 



1 Deca =10 pendulums 



1 Pendulum... = 1 pendulum =39*13047 inches 



1 Deci = '1 do. 



1 Centi = -01 do. 



1 Milli = -001 do. 



From this long measure proceeds that of liquid. The gallon 

 at present in use contains 268 803 cubical inches, and is re- 

 commended by the present committee to contain 276"48 cu- 

 bical inches, or 10 lbs. avoirdupois, being 3 per cent, larger; 

 thus making the half-pint to contain 10 oz. or 17'2S cubical 

 inches of pure water of 56|° by Fahrenheit's thermometer. This 

 gallon is by the' above bill divided into four quarts, eight pints, 

 sixteen half-pints, though it would be a much enlargement of this 

 gallon : yet to have a strict comparison we might make it to con- 

 tain ten cubical pendulums, or equal to 391*3047 cubical inches. 

 With this scale, 



1 Kilogallon . . = 1000 gallons 



1 Hecto = 100 do. 



1 Deca = 10 do. 



1 Gallon .... = 1 gallon =10 cubic pendulums 



1 Deci = -1 do. 



1 Centi = *01 do. 



1 Milli = -001 do. 



From these measures proceed weights. It has been already 

 seen that the gallon contains 10 lbs. pure water, whence lib. 

 pure water is equal to 27"648 cubical inches, according to the 

 standard named by the said bill; which pound is by the same di- 

 vided into 16 oz. each ounce of 16 drachms 48 scruples, or 480 

 grains. Now, for the reasons before stated, let this pound con- 

 tain 1-lOth of the gallon, or one cubical pendulum of pure wa- 

 ter, thus : 



1 Kilopound.. =1000 pounds 



1 Hecto = 100 do. 



1 Deca = 10 do. 



1 Pound = 1 pound, or I cubical pendulum 



1 Deci = * 1 do. 



1 Centi = -01 do. 



1 Milli = *001 do. 



From the above measures the square measures might be de- 

 rived. With regard to assaying metals, let both the carat and the 

 ounce be abolished, and have another carat to be subdivided ir»to 

 1000 parts, to be used both for gold and silver. 



The next point I have to notice is the coinage. In this case 

 also I would recommend a regular conformity with the weights 

 and measures. This however might be laid over for the direction
