these acts, and directed to contain 10 lbs. avoirdupois of distil- 

 led water, at 62° of heat, the barometer being at 30 inches ; the 

 same being in bulk equal to 277'274 cubic inches ; and all other 

 measures are to be taken in parts or multiples of the said gallon. 

 The quart to be one-fourth part of the gallon, and to contain 

 69"3 185 cubic inches, or 2| lbs of water. 



The pint to be one-eighth part of the gallon, and to contain 

 34"6o92o cubic inches, or l± lb. of water. 



Two gallons to be a peck, and to contain 554-748 cubic inches, 

 or 20 lbs. of water. 



Eight gallons to be a bushel, and to contain 2218-192 cubic 

 inches, or 80 lbs. of water. 



Eight bushels to be a quarter of corn, or other dry goods. 

 No particular form or proportion is directed for the bushel or 

 other measures used for corn or other goods, usually sold by 

 strike measure. The strike is directed to be round and straight, 

 and of the same diameter from end to end. 



The standard for coals, lime, fruit, and other goods, commonly 

 sold by heaped measure, is the aforesaid bushel, to be made 

 round (we must presume cylindrical), with a plain and even 

 bottom, and nineteen and a half inches diameter from outside to 

 outside ; and when used, to be heaped in the form of a cone ; 

 such cone to be of the height of at least six inches, the outside 

 of the bushel being the extremity of the base of such cone ; and 

 including the cone, it will contain 2815.4887 cubic inches, which 

 gives 597.2967 cubic inches, being 26 and 12-13ths per cent, or 

 2 and 2-13ths of a gallon above the corn bushel, for the contents 

 of the cone. 



All other measures used for coals and other goods, sold by 

 heaped measure, are to be made cylindrical, with the diameter 

 at the least double the depth thereof, and the height of the cone 

 three-fourths the depth of the measure. 



The proportion that the new imperial measure of capacity 

 bears to the various old measures is as follows : 



— 1-9492, say a fifth part, or 20 percent, larger than the wine 

 measure. 



1 — 59-67, say a sixtieth part, or If per cent, smaller than the 

 beer measure, which ditt'erence is equal to little more than one 

 cubic inch in a quart. 



This difference from the old coal measure will be very trifling, 

 it being only 3-5tlis of a pint larger in a chaldron. 



A furtlier alteration is made, by inference, from the declared 

 proportions of the weight and cubical contents of the imperial 

 gallon, which is interesting to scientific men; viz. that the spe- 

 cific gravity of water, hitherto established at 1000 ounces per 

 cubic foot, is now calculated at the rate of 997-1364 ounces per 

 foot. — (Scientific Gazette.)
