instance was a piece of a darning needle. In probing a 

 punctured wound of the sole or frog, none but a sterilized 

 probe should be employed and that only after the wound 

 has been disinfected. 



5.— Pricking in Shoeing. 



Inspection. — "When the nail is driven into the deep layers 

 of the podophyllous membrane, lameness is either immedi- 

 ate or may be severe within the next twenty-four hours. 

 Such a case, seen soon after the shoe has been nailed on, 

 generally shows a little blood around the clench of the 

 pricking nail. If the nail is only driven too close to the 

 rete malphigii, thus simply exerting pressure, three to five 

 days may elapse before sudden lameness, Math all the 

 symptoms of a superficial inflammation of the podophyllous 

 membrane, becomes apparent. 



Palpation. — Lightly tapping the head or clench of the 

 offending nail immediately makes the animal flinch, and 

 upon removal, the nail will show pus or blood adhering to 

 it. Paring of the white line reveals a black spot (the stain 

 is chiefly due to precipitated sulphide of iron), extending 

 somewhat into the sole. This discoloration always indicates 

 that the nail entered the podophyllous membrane. 



6— Corns. 



Are reddish, or occasionally yellowish spots, situated 

 chiefly in the angle formed by the bars and the wall, which 

 do not produce lameness unless the bruising agent continues 

 to act, — the product of the resulting contusion pressing 

 upon the sensory nerves of the podophyllous membrane, — 

 or septic inflammation takes place. The septic material 

 enters at the place where the so-called corns are located, so 

 often the case when they are cut out. This inflammation is
