STATISTICAL STUDY OF BODY WEIGHTS 328 



Of the initial measurements the greatest coefficient of varia- 

 tion is 11-9 ± 0-04 per cent for initial live weight. In all the 

 chest measurements the coefficients of variation are relatively 

 high : Width at point of shoulder 9-3 ± 0-52, width of fore 

 flank 10-4 ^ 0-6, depth of chest 6-1 J- 0-34, and circumference 

 of chest 6-9 ^ 0-39. Likewise the mid and posterior regions of 

 the body show variations, the rear flank with a coefficient of 

 variation of 8-7 ± 0-48, circumference of rear flank 6 i 0-34. 

 width of loin 7-5 ± 0-43, width of thurls 5-9 ± 0-34, circum- 

 ference of paunch 11 + 0-62. and distance of hips to buttock 

 5-2 ± 0-29.
