with a knot at the farther end of it, through the opening near the point, 
and withdraw the instrument, leaving the tape in after another knot has 
been tied at the other extremity. 
Thus a seton is established, and a depending orifice is instituted. 
The tape will act as a drain to the morbid secretion, while the irritation 
produced by it will also remove the callous lining of the pipe. A 
healthy action will thereby be established; and so soon as the inferior 
wound discharges a fall stream of thick, creamy pus, the seton may be 
cut out, with a conviction that its office is fulfilled. 
Tis SETON NekbLi PROTRUDED, AND SECURED WITHIN THE HANDLE BY MEANS OF A SCREW. 
The screw being loosened, the button is struck, and the sharp needle shoots forward, cutting its way 
through any interposing obstacle.

considered how much the happiness of the lower order of beings de- 
pends on merely feeding and living, it will be at once apparent how 
much the horse has lost when all enjoyment has departed from eating ; 
when mere existence is embittered by being a prolongation of the suf- 
fering. The digestion becomes deranged, because the saliva, or a
