‘The advantages of this method of fastening have been 
found to be: (1) It does not chafe the skin; (2) if properly 
applied it has never been known to come undone; (8) it 
is the only way we know that_a poultice can be satis-

These have an objection. They are apt to be allowed to 
get extremely dirty, and so, by carrying infective matter 
from the foot of one animal to that of another, undo the 
good that the warmth of the poultice is bringing about. 
The advantage of the ordinary sacking or canvas is that it 
may be cast aside after the application of each poultice.
