WOUNDS 247 



The only method of treatment that can be practised, 

 therefore, is that of palliation. Seeing that the trouble the 

 veterinary attendant will have to deal with is loss of a 

 portion of the weight-bearing surface, his attention is im- 

 mediately directed to the shoeing. As with sand-crack, so 

 with false quarter, the frog and the bars must be called 

 upon to take more of the body-weight than commonly they 

 do with the ordinary shoe. The indication, then, is a bar 

 shoe. At the same time, the bearing of the wall on the 

 shoe on either side of the fissure should be eased by slightly 

 paring it, and the hypertrophied horn on the outer surface 

 of the wall removed with the rasp. 



In cases where penetration of the sensitive structures 

 has occurred, complicated with the formation of pus, the 

 same treatment as for complicated crack is to be followed. 

 The foot should be poulticed for several days with hot anti- 

 septic dressings, and thorough cleansing of the infected 

 parts brought about. Afterwards strong solutions of suit- 

 able antiseptics should be applied daily until such time as 

 the horny covering has renewed itself. This done and the 

 bar shoe applied, the fissure may be plugged with any 

 effectual stopping. Either a mixture, such as Percival's, of 

 pitch 2 parts, tar 1 part, and resin 1 part, melted and 

 mixed together, or one of the artificial hoof-horns may 

 either be used with advantage. 



E. ACCIDENTAL TEAEIXG OFF OF THE ENTIRE 

 HOOF. 



Causes. — Seeing that this accident to, and consequent 

 severe wounding of, the keratogenous membrane nearly 

 always occurs in but one way. it is worthy of special men- 

 tion. So far as we are able to ascertain, it is an accident 

 peculiar to horses continually engaged in shunting opera- 

 tions either in pits or station-yards. At the moment the 

 animal is released from the waggon he has been pulling, 

 and should turn to the right or the left in order to allow it 

 to pass him, the shoe either becomes wedged in between two 

 converging rails, or is trapped by the wheel of the waggon.
