veterinarian as a rule does not see the case until more 

 definite symptoms have developed, which is usually 

 on the second or third day. The cow now lies down 

 most of .the time. If she is sufficiently urged by prod- 

 ding or whipping she can usually be made to ^et up on 

 her feet. This is a good point to have in mind in case 

 the attack has occurred soon after calving, when it 

 would be necessary to exclude parturient paresis. 



When the cow has assumed the standing position 

 she constantly shifts her weight from limb to limb ;
