190 DISEASES OF 



Symptoms. Coughing attracts, early attention; if th& 

 animal is made to move, a fit of coughing is sure to oc^ 

 cur. There is a thick discharge of mucus from the nos- 

 trils, and the worms are often found in it. As the dis- 

 ease advances the animal becomes greatly weakened 

 and loses condition ; the breathing becomes labored, 

 and all the symptoms of pneumonia may be present. 

 The animal looks dull and stupid and does not care to 

 move. 



Treatment. To prevent infection, sheep should be 

 kept on new pastures. The old pastures on which 

 infected sheep have been kept will contain the eggs of 

 the worms, which will reach the lungs after being 

 taken in with the food. The fumes of sulphur is about 

 the best remedy after the disease has once got a foot- 

 hold. The sheep must be placed in a closed building, 

 and a small quantity of sulphur set on fire. This will 

 produce hard fits of coughing, during which large 

 numbers of the worms will be expelled. The animals 

 must not remain in the sulphurous atmosphere more 

 than ten minutes, as there is danger of suffocation. 

 Another good remedy is the following : Oil of tar 1 oz., 

 oil of turpentine 1 oz., sweet oil 6 ozs. Give 10 to 20 

 drops in the nostrils daily. 



CENURUS CEREBRALIS. 



This worm produces the disease in sheep known as 

 Gid, Turn-Sick, Hydatid on the Brain. The cenurus 

 cerebralis is the cystic form of the tenia cenurus, which 

 is one of the common tape-worms of the dog. In Fig. 

 91 is seen a cyst containing a number of the eggs of 

 this worm. These cysts are found in the brain, and are 

 the cause of the curious symptoms seen in gid. In Fig.
