 Ws. and Measures : The U. S. Standard Unit of 

 Weight is the Troy Pound ; it was copied in 1827. 

 from the imperial troy pound of England, for the use 

 of the U. S. Mint, and there deposited. It is standard 

 in air, at 62 Fah., the barometer at 30 inches.

The Standard Unit of Liquid Measure adopted by 

 the U. S. Government is the Winchester Wine 

 Gallon, which contains 231 cubic inches, and holds 

 8.339 ^ 5 avoir, of distilled water, at its maximum den- 

 sity, weighed in air, the barometer being at 30 inches. 

 The Imperial Gallon adopted by Great Britain con- 

 tains 277,274 cubic inches, and equals 1. 20032 U. S. 

 gallons. The Standard Unit of the U. S. and British 

 Linear Measure is the yard. It was intended to be 

 exactly the same for both countries, but in reality the 

 V. S. yard exceeds the British standard by .00087 

 inch. The actual standard of length of the U. S. is a 

 brass scale 82 inches long prepared for the Coast Sur- 

 vey and deposited in the Office of Weights and 

 Measures at the U. S. Treasury Dept., Washington. 

 The yard is between the 27th and the 63d inch of this 

 scale. The temperature at which this scale is designed 

 to be standard, and at which it is used in the U. S. 

 Coast Survey, is 62 Fahrenheit.
