NORMAL DENTITION 



This calf's teeth are normal, though it was sired by the same bull (see Fig. 6) as the 

 calf with defective dentition shown in Fig. 7. There are four sharp, well-formed in- 

 cisors on each side in the front of the lower jaw. (Fig. 8.) 



A DEFECTIVE COAT 



This calf is the same one whose mouth, with defective dentition, is shown in Fig. 7. The 

 smoothness of the coat on the head and upper neck is due to the very short hair on 

 these parts. This characteristic is probably correlated with defective dentition, and 

 appears to be inherited. (Fig. 9.)
