366 Abstract of the Weights and Measures Act. 



(as has been done with regard to the troy and avoirdupoise 

 pound, and the yard and foot), and defining and legalizing of 

 the other units of the principal systems of measures in use y 

 like the corn and the coal Bushels and their multiples and sub- 

 multiples, the wine and the beer gallons, and their mults. and 

 submults. &c, is all which myself or the present race of your 

 readers have, I fear, any reason to expect to see realized.

Abstract of an Act of the last Session of Parliament for regida- 

 ting Weights and Measures. 



By the Act 5 Geo. IV. Cap. 74-. " For ascertaining and 

 establishing uniformity of Weights and Measures," it is enact- 

 ed, that from and after the 1 st of May, 1 825, the standard brass 

 yard made in 1760, at the temperature of 62° by Fahrenheit's 

 thermometer, shall be, and be denominated, the " Imperial 

 Standard yard," and shall be the unit or only standard mea- 

 sure of extension, whereby all other means of extension, whether 

 lineal, superficial, or solid, shall be computed and ascertained 

 according to the proportions for certain measures of extension 

 specified in the act. 



And that if the said imperial standard yard shall be lost or 

 injured, it shall be restored by making a new standard yard, 

 in the portion of 36 inches to SS^ou^ inches, when compared 

 with a pendulum vibrating seconds of mean time, in the lati- 

 tude of London, in a vacuum, at the level of the sea. 



Also, that after the 1st of May, 1825, the standard brass 

 weight of one pound, troy-weight, made in the year 1758, shall 

 be the " Imperial Standard troy pound," and shall be the 

 unit or only standard measure of weight, from which all other 

 weights shall be computed and ascertained, according to the 

 proportions for certain other weights specified in the act. 



And that if the said imperial standard troy pound shall be 

 lost or injured, it shall be restored by making a new standard 

 troy pound, bearing the same proportion to the weight of a 

 cubic inch of distilled water as the said standard pound, there- 

 by established, bears to such cubic inch of water; that is to say, 

 5-760 cubic inches of distilled water, weighed in air, at the 

 temperature of 62° of Fahrenheit's thermometer, the barome- 

 ter being at 30 inches, each such cubic inch of water, when so 

 weighed by brass weights, being equal to 252 y 4 ^ grains, and 

 that 7,000 such grains shall be one pound avoirdupoise. 



It further enacts, that after the 1st of May, 1825, the standard 

 measure of capacity, as well for liquids as for dry goods, not 

 measured by heaped measure, shall be the gallon containing ten 



pounds
