Most persons know what bellyache and cramp are. Well, these are but spasms affecting different parts of the body: tetanus is spasm affecting every part of the body at the same time. The spasm is always present; but it admits of aggravation. Any painful operation, any sudden fright, or the slightest sound, will produce a paroxysm, during which the horse's body is fearfully contorted; and the animal writhes as it falls to the ground. Left alone, however, the horse may rise after some time; for nothing causes the quadruped so much dread as an inability to stand. It may totter or fall about, but it refuses to lie down, even though rest must be greatly needed and would act as the best of medicine. It stands day after day in the same spot. It does not move, as any motion may bring on one of those terrible paroxysms. The matter is rendered worse by the brain, during the entire period, being sensible. Every pain is felt, and the wretched animal has leisure to appreciate its agony. This is bad enough; but the torture is aggravated by the appetite of the animal not being dormant. Hunger still exists, and a sense of starvation augments the suffering. The jaw is closely locked. The creature cannot feed; but the presence of hunger is no supposition, for if a mash be held to the mouth, with a look of piteous gratitude the liquid portion is often drawn through the closed teeth. Hunger frequently impels the horse to make a desperate effort. The jaws are forced a little way asunder; a morsel is seized between the incisors; mastication commences, but cannot be perfected. The agony attendant upon motion forces the famishing creature to desist; and the poor horse is often found with a mouthful of hay firmly clenched and hanging from the mouth. [Illustration: SHOWING HOW FAR AN ANIMAL WITH THE DISEASE IS CAPABLE OF MOTION.] The animal may have been conspicuous for its beauty. The harmony of form may, in it, have been united to agility of limb. The creature may have been the pride of its proprietor; but a few days of this disease will work a mighty change. The limbs are moved with difficulty; the body has lost all its undulating grace; and the flesh has parted with its elasticity. The master in vain seeks for the object of his admiration in the painful sight which he then looks upon.
