enough. With lacerated wounds the treatment is very 
similar. Jf the wound becomes inflamed and spongy, 
add a tablespoonful of acetate of lead and a tablespoonful 
of sulphate of zinc to the antiseptic solution and apply 
twice daily. 
10. Nail puncture—If an animal becomes suddenly 
and severely lame and there is no evidence of an injury 
to any other part of the leg, such as swelling, heat and 
pain upon pressure, it is always well to look for puncture 
in the foot. If the animal stands with the lame foot ex- 
tended, and when walking places the lame foot well for- 
ward and brings the well foot up to it, the evidence of 
puncture is still stronger. To examine the foot prop- 
erly the shoe should be removed. It is not sufficient to 
merely scrape the bottom of the foot clean, for if the nail 
has pulled out and the horn sprung back in position, all 
trace of its entrance may have been obliterated. To ex- 
amine the foot properly, tap the hoof with a hammer or 
knife and the exact spot may be definitely located. If 
the injury is of a few days’ standing, additional heat in 
the hoof, and, perhaps, slight swelling 
of the coronet may also be present. 
Locating lameness in the stifle joint is a 
common but inexcusable error, as the action 
resulting from lameness in the two parts is 
entirely different. The so-called gravel, 
which is said to enter the sole of the foot 
and then to work out at the heel, is usually 
the working out of the pus or th matter 
resulting from a nail‘puncture or a bruise.
