have to he done twice in the day, till no more pus can be brought 

 out. 



Occasionally syringe or squirt cold water into the sore, and 

 swab it out again, till completely dry. Then apply the following, 

 once in a day, with a swab : Creosote, one ounce ; oil of olives, 

 two ounces ; oil of turpentine, one ounce ; mix. In applying the 

 mixture do not use the swib too freely, as it may break down the 

 granulations or the healing processes that are springing up to fill 

 the hole or cavity, and thereby prevent a perfect cure. 



When poll-evil is the result of diseased bone, and partakes of a 

 fistulous character, it will not be so easily healed er cured ; for 

 the underlying bone being carious, and becoming necros<(d, be* 

 fore exfoliation or separation of the dead bone takes place the 

 horse may be dead — the process taking years to perfect itself. 

 And when it is cured, there is usually a stiff peck remttining ever 

 after. Ten drops of sulphuric acid poured in the fistulous open- 

 ing of the swelling or sore will hasten recovery vefy much and in 

 many cases effect a good and speedy cure. Once a day will be 

 often enough, and if there be more than one fistulous opening, 

 drop the acid into pne to-day and the other to-riaorrow, and con- 

 tinue from day to day, till each and every opening ceases to 

 discharge a whitish gray matter, and a dry looking opening is 

 presented. Afterwards, use a solution of the sulphate of zinc : 

 one drachm of the zinc to four ounces of water, will answer the pur- 

 pose. Horses having sores of all kinds on their body should be 

 well fed and cared for. 



Polypi. — These are diseased enlargements, which grow upon 

 the mucous membranes of the nose and ear, and in the uterus or 

 womb of mares. 



Treatment. If they are small, they are cured by touching them 

 with a stick of caustic potassa ; if large, cut them off with a sharp 

 knife or scissors, and apply a weak solution of blue stone to tba 

 sore till it is healed. 



Predisposing Causes. — Causes which render an animal sus' 

 ceptible to disease. For example, a young horse standing in the 

 stable from day to day becomes predisposed to disease of th« 

 throat and lungs, when put to any exertion. Old age is a predis- 

 posing cause of disease. Some animals, as well as men, are mon
