water should be used, and tlie food should be of a cooling nature, 

 such as bran mashes, etc. 



Sub-acute and chronic laniinitis is caused by hard work and 

 irregular exercise. The symptoms are those of the acute form 

 modified. The treatment, more tedious than that of the acute 

 form, is the same,. except that a blister should be apj^lied to the 

 coronet in the chronic form. 



PUMACED FOOT 



Is that condition of the foot in which the coffin bone descends. 

 This condition occurs as a result of laminitis. It may also be 

 caused by improper 

 shoeing. The os 

 pedis, in some cases, 

 may force its way 

 through the sole; in 

 such case the animal 

 should be destroyed. 

 The treatment 

 consists of removing 

 the shoes, rest, poul- 

 tices. A bar or 

 round shoe should 

 be applied, so that 

 it will bear alto- 

 gether on the wall 

 and frog, and not on the sole. A horse suflfcu-ing from this dis- 

 ease will do very well for work on a farm, l)ut cannot do fast 

 work. 



INFLAMMATION OF THE CORONARY SUBSTANCE. 



Symptoms. — Harshness and brittlencss uf the crust; loss of 

 toughness and pliability; increased heat round the coronet and 

 upper part of the crust; diminished secretion of horn, and a pecu- 

 liar striated condition of the crust. The horse glides his feet 

 along the ground. The duration of this disease is a few weeks.
