STATISTICAL STUDY OF BODY WEIGHTS 319 



lots was done with rations affording very nearly the same 

 opportunity for gains in live weight and condition of flesh for 

 marketing. 



Table I includes all records for the three years, while the 

 correlation tables include the data during the first two years. 

 All body measurements except circumferences were made with 

 the steel caliper ; all circumferences were measured with a 

 steel tape graduated in inches. The probability of error in 

 measurements is a factor not considered, thus necessitating a 

 large number of measurements to reduce the probable error.

 old steers fattened for market during a 140 -day feeding period.
