Diagram IV. shows graphically how very little difference 

 there is between the two groups of animals. 



(iv.) The next diagram (V.), again dealing with the wedge- 

 shape, contrasts the width of the cow at the front of the chine 

 and at the widest part of the ribs. Considering the anatomical 

 structure, these measurements must be looked upon with a 

 critical mind, for in the case of the rib's measurement we 

 have only rib, flesh, and skin of the animals between the

Group E. — Slope I in 2 "41.

points, but at the chine we have rib, skin, flesh, and shoulder 

 blade bone. They are interesting however, for when judging 

 a cow by inspection the eye would naturally follow the lines 

 formed by joining up such points. It will be seen by 

 Diagram V. how very similar the wedges are found to be. 



It has been further held that another "point " in a milch-cow 

 is that she should be deep in the body. The following figures 

 give the average depth and height of the cows (in inches) in 

 Groups A and B and the ratios between these measurements.

Length of quarter, i.e., from hook to pin-bone, is also 

 claimed as a good "point," and the following measurements
