_Symptoms._--A rough, staring coat; hide-bound; painful cough; respiration hurried, etc. _Treatment._--But little can be done by way of treatment in this disease. The administration of small doses of spirits of turpentine has, in some instances, proved successful. SURGICAL OPERATIONS. CASTRATION. The period most commonly selected for this operation is between the first and third months. The nearer it is to the expiration of the first month, the less danger attends the operation. Some persons prepare the animal by the administration of a dose of physic; but others proceed at once to the operation when it best suits their convenience, or that of the farmer. Care, however, should be taken that the young animal is in perfect health. The mode formerly practised was simple enough:--a piece of whip-cord was tied as tightly as possible around the scrotum. The supply of blood being thus completely cut off, the bag and its contents soon became livid and dead, and were suffered to hang, by some careless operators, until they dropped off, or they were cut off on the second or third day. It is now, however, the general practice to grasp the scrotum in the hand, between the testicles and the belly, and to make an incision in one side of it, near the bottom, of sufficient depth to penetrate through the inner covering of the testicle, and of sufficient length to admit of its escape. The testicle immediately bursts from its bag, and is seen hanging by its cord. The careless or brutal operator now firmly ties a piece of small string around the cord, and having thus stopped the circulation, cuts through the cord, half an inch below the ligature, and removes the testicle. He, however, who has any feeling for the poor animal on which he is operating, considers that the only use of the ligature is to compress the blood-vessels and prevent after-hemorrhage, and, therefore, saves a great deal of unnecessary torture by including them alone in the ligature, and afterwards dividing the rest of the cord. The other testicle is proceeded with in the same way and the operation is complete. The length of the cord should be so contrived that it will immediately retract, or be drawn back, into the scrotum, but not higher, while the ends of the string hang out through the wound. In the course of about a week, the strings will usually drop off, and the wounds will speedily heal. There will rarely be any occasion to make any application to the scrotum, except fomentation of it, if much swelling should ensue. A few, whose practice cannot be justified, seize the testicle as soon as it escapes from the bag, and, pulling violently, break the cord and tear it out. It is certain that when a blood-vessel is thus ruptured, it forcibly contracts, and very little bleeding follows; but if the cord breaks high up, and retracts into the belly, considerable inflammation has occasionally ensued, and the beast has been lost.
