170 HORSESHOEING. 



be kept warm. Antiseptic solutions at room temperature are 

 much less efficient. 



If the pain has not been very pronounced, or if it has been 

 greatly alleviated by two or three warm baths, then, as a rule, 

 it is sufficient to put a few drops of creolin upon the inflamed 

 surface, and to close the opening with oakum (carbolized oakum 

 or carbolized cotton is better). 



The horse which has been nailed will be again perfectly 

 serviceable after a few days if shod with a shoe which does not 

 press upon the inflamed region. The shoe does not press when 

 it rests only upon the hearing-edge of the wall, when the white 

 line and the edge of the sole are entirely free of the shoe, and 

 no nails are driven in the immediate vicinity of the wound. 



Even though, as we have seen, nailing in the great majority of 

 cases is not particularly serious to the horse and owner, yet we should 

 never forget that tetanus (lockjaw), a disease which is nearly always 

 fatal to horses, may follow. Nailing, however insignificant it may 

 seem, may under conditions lead to the death of the horse. 



2. Street-Nail. 



The condition caused by accidental injury of the sensitive 

 'structures covered by the homy sole, such as the velvety tissue 

 of the sole and frog, plantar cushion, perforans tendon, navicu- 

 lar bone, OS pedis, or the pedal articulation, by sharp objects, 

 especially nails, is called " penetrating street-nail," or simply 

 " street-nail." The resistance of the ground to the weight of 

 the body drives these penetrating objects through the sole or 

 frog into the foot. 



Hind hoofs are more often affected than fore-hoofs. A 

 favorite point of entrance is the lateral lacuna of the frog. 

 Street-nail is favored by excessive thinning of the sole and 

 frog. 



Symptoms. — The symptoms are, as a rule, sudden pain fol- 

 lowed by lameness. The first a^ssistance is usually sought in 

 the shoeing-shop. If the cause of lameness be found to be a
