_Symptoms in_ =Cattle=. In cattle the animal is attacked without premonition, bellows, breathes hard and with effort, has dilatation of the nostrils, and squinting or rolling upward and backward of the eyes and falls to the ground rigid and trembling. There may be violent succussions of the limbs, head or neck, movements of the jaws, grinding of the teeth, and the appearance of frothy saliva and elements of food about the lips. The beats of the heart are violent, the pulse slow and small, and sometimes intermittent. Involuntary micturition, defecation, or discharge of semen may occur. In slight cases one or more of these symptoms may be absent, and the victim may not even fall to the ground but support himself against a wall or other object. The duration of the attack may be from one to five minutes, rarely more, and there is often a slow and progressive subsidence of the spasms. When recovered the animal may get up and go to eating or rumination as in health. _Symptoms in_ =Sheep=. In sheep the attack is sudden. The animal ceases eating or stops in its walking, and after turning or other involuntary movement falls to the ground, head extended, mouth open, eyes rolling or squinting, and with rigidity or twitching of the muscles of the neck or limbs. There is the same loss of sensation, frothing from the mouth, and grinding of the teeth as in the larger animals. The attack may last 40 to 50 seconds. _Symptoms in_ =Swine=. In pigs a state of discomfort and restlessness often marks the approach of an attack, referable probably to the digestive disturbance or to parasites which furnish the occasion of the disease. Uneasy, wandering movements, jerkings of head or limbs, rolling of the eyes, and champing of the jaws may first appear. Then the animal falls, extending its limbs and head, with open mouth, retracted lips, and a free flow of saliva. Trembling and jerking of the head, neck and limbs, hurried, short, difficult breathing, and complete loss of sensation may be noted. Discharges of urine, semen, and prostatic fluid are not uncommon. The attack usually lasts 2 or 3 minutes, and exceptionally 10 to 15. In the shorter seizures, frequent repetition is not uncommon, Delafond having observed 5 or 6 attacks in the course of an hour.
