8ore Feet. Causes.— If hogs are kept continually on hard floors or 

 driven over hard, rough i-oads the feet may become intlamed and bruised. 

 Standing iu tilth may cause tlie feet to become sore, the moisture soften- 

 ing the tissue at the upper margin of the wall, in the iutcrdigital space 

 and at the heel. 



Symptoms.— The hog flinches a great deal when it walks, goes quite 

 lame. This is especially true of heavy hogs. If the pain is severe it may 

 lie down most of the time. On making a local examination, the claws 

 may he found long and overgrown at the heel and the space between 

 the claws is swollen, sore and inflamed. 



Treatment.— AVhen caused by hard floors simply turning them out on 

 pasture will effect a cure. If the pens and yards are ttlthy, they should 

 t)e changed to clean, dry pens and the feet freed from all filth, and 

 washed once a day with a watery solution (four per cent.) of some of 

 the cresol preparations; or with chloride of zinc (one teaspoonful to the 

 pint of water). It is very necessary that the hogs be kept in a clean, 

 dry place until well. 



Difficult Parturition.— DitHcult birth is not as common in the sow av 

 in the larger domestic animals. This is because the pelvic cavity through 

 which the fietus passes is large in comparison with the size of the young. 

 A roomy ])elvic cavity, however, does not ahvays insure an easy birth, 

 and when the laws of nature are ignored and but little attention paid to 

 the hygiene of pregnant animals, there will be plenty of cases of difficult 

 parturition. 



Causes.— The most common cause of diflicult iiartiuition in young and 

 fat sows is a large fcetus and a nairow maternal passage. Breeding 

 young, small sows to larg(! males is a fretiuent cause. > Other causes 

 are malpresentations, monstrosities, and diseases of the foetus (hydro- 

 cephalus, emphysemia, etc.). Emphysematous conditions are met with 

 when the act of parturition has been prolonged and the foitus is dead 

 and undergoing decomposition. The only malpresentation met with is 

 the transverse. In this presentation instead of the head or breech pre- 

 senting it is the side, back, or belly. In prolonged parturition the ma- 

 ternal passages become dry and the passage of the foetus along them is 

 greatly interfered with. In case of debility and exhaustion, the expelling 

 powei-s are weak in comiiarison with the resistance to be overcome, and
