98 PRACTICE OF EQUINE MEDICINE. 



fracture of the bones of the hind extremity or of the pelvis is the 

 result. The pelvis is apt to break down when the foetus is present. 

 Fracture of ribs may take place. 



What is the prognosis? 



The prognosis is favorable if seen early and the proper kind 

 of food is given. If the disease is allowed to go on, the animal 

 dies of asthenia. 



Eoloff says that these fractures get well by the formation of 

 a callous, while others say a union rarely takes place; false joints 

 are formed. 



The fractures in these instances are painless.

 the feed. The linseed oil may be substituted by cod-liver oil. 



Give nitrogenous food, rich in calcareous salts, grains in the 

 shape of oats or dry clover; fruit is also very beneficial. 



Oil-cake prepared with the food may be used. Then, again,

EICKETS. 



Name the synonyms. 



Eachitis, bone softening. 



Define Rachitis. 



This is a general or constitutional disease, affecting nutrition, 

 and characterized by a lacli of calcareous salts in the bone, pro-

What is the aetiology? 



This is a disease of youth, and the animal may be born with
