Poisoned Wounds are for the most part due to one or another of the various micro-organisms which gain an entrance to them. In addition there are the stings of insects, such as bees and wasps, which sometimes attack our horses, and produce serious mischief. In these cases the stings must he removed, as far.as possible, and the part dressed with ammonia.

Snake-bites, which happily are of rare occurrence in this country, are occasioned by the introduction of a secretion formed in the fangs of the teeth of the snake, and injected into the tissues in the act of biting. Except in the Common Adder (Pelias berus) we have no venomous reptiles in this country, and the poison from this creature is comparatively feeble and harmless. In snake-bites, treatment, to be effective, must be prompt; a ligature should be tied tightly round the part, above the wound, which should be laid open and encouraged to bleed freely; excision of the bitten part, and the application of lunar caustic, or the actual cautery may also be resorted to.
