28 DISEASES OP SHEKP. 



membranes of the mouth become of a blood-red color ; the 

 animal involuntarily loses its excrements and urine, which 

 latter is often covered or mixed with blood ; the animal at 

 the same time kicking and throwing the legs about, turning 

 head and neck backward, the breathing often causing a 

 rattling noise, and a bloody scum issuing from the mouth. 

 Such attacks are often of only five or ten minutes' duration, 

 after which they result in death. This is especially the case 

 with young sheep ; old sheep sometimes resist several of 

 these attacks, and then die after a few hours. If death 

 does not occur after such attacks, the animal becomes very 

 weak and inanimate, the ears and legs being cold. Such 

 sudden attacks are often followed by a gentle and soft ex- 

 piration of life ; the animal is often restless during the 

 night, and its body is then in the morning found to be life- 

 less. In case such disease is of longer duration, the animal 

 is observed to remain, apart from the herd, deeply drooping 

 the head, the walk being inanimate and weak, the ears 

 hanging downward, the neck swollen, the blood-vessels of 

 the eye extended and filled with dark-colored blood ; the 

 mucous membranes of the mouth are of a blood-red color, 

 the dung is hard and covered with bloody slime ; and the 

 perspiration produces an adhesive matter of a very bad 

 smell. At last the animal begins to reel and tumble with 

 convulsions ; blood flows from the nose, mouth and anus. 

 In case of venesection, the blood flows easily and is of a 

 dark-red color. In such cases death generally ensues in 

 from one to three days, seldom later. When an animal 

 becomes afilicted with this disease, it often happens that 

 upon several places of the skin (especially upon such 

 places as are little covered with wool, as, for instance, the 

 belly, the udder and the inner side of the shanks) there ap- 

 pear certain erysipelatous freckles, which in the beginning 

 are of the form of small knots, and rapidly increase in size
