The following short account of the method of calculating the 

 weight of animals by the pen, and constructing the Table, may 

 be found useful. 



It has been ascertained, by a number ot experiments, that if 

 the girth and length of cattle are taken as formerly directed, and 

 the solid content found by the rule for calculating the solid con- 

 tent of cylinders, each cubic or solid foot will indicate a weight 

 of 3 Imperial stones, and the third part of a cubic foot, or 576 

 cubic inches, will consequently be equal to 1 stone. If, there- 

 fore, the whole content in cubic inches is divided by 576, the 

 quotient will be the number of Imperial stones in the four quarters 

 of the animal. 



RULE 1. Multiply the square of the girth of the animal by the 

 length, both in inches, and the product, multiplied by the decimal 

 .07958, will give the content in cubic inches; which divide by 

 576, and the quotient is the weight of the animal in Imperial ! 

 stones of 1 4 Ibs. 



2. Multiply the square of the girth by the length, both in 

 inches ; and divide the product by 7238, and the quotient is the 

 weight in Imperial stones. 



3. Multiply the square of the girth by the length, both in 

 inches, and that product multiply by the decimal .00013816, tin 

 product is the weight in Imperial stones.
