DISEASES OF THE OX AND SHEEP. 267 



of the head. Moreover, the animal occasionally gives utterance 

 to a short husky and painful cough, which may be brought on 

 by causing rapid movement. The animal may grind the teethe 

 The tail appears to be paralysed. Only about half of the 

 sheep which are affected suffer from diarrhoea. They soon look 

 very emaciated, nearly always assume the recumbent posture, and 

 when they rise, do so with great difficulty, and stagger about 

 helplessly to and fro. Their eyes are almost closed, and in some 

 sheep spots may be seen on the perineum and udder and in other 

 parts. 



At times they appear to be very near death, but even then 

 they usually recover. The eyes assume a more lively look ; on 

 the following day the animal may eat a little and manifest thirst ; 

 the pulse and respirations become fairly normal again ; there is 

 no coughing ; and, finally, the discharge from the nostrils and 

 the formation of crusts disappear within about eleven days from 

 the outbreak of the disease. If, on the contrary, the sheep or 

 goat should die, it will generally be at about the middle of the 

 third day that death will occur, although it may sometimes 

 happen that convalescent animals may perish as a result of 

 exhaustion at about the fourteenth day. 



MEASLES IN SHEEP. 

 So commonly is measles supposed to be a complaint affecting 

 children only that perhaps some persons may scarcely suppress 

 a smile when they read that sheep are liable to suffer from 

 that disease. "When thus afflicted, these animals manifest slight 

 signs of fever — sneeze, cough, give forth a discharge from the 

 nostrils, and swell in the region of the head, and especially near 

 the parotid gland. The mouth is hot, the skin dry, and the 

 animal is constipated, and exhibits little or no inclination for 

 food. Towards the close of the second day after the beginning 

 of the illness, an eruption of red and irregular spots appears on 

 the chest, then on the thighs, the sides of the body, and the face. 

 When these spots are pressed upon by the finger, they are felt 

 to be hard in the centre, and after removal of the pressure they 

 are seen to have lost their red colour for a time and to have 

 become white. The secretion of the skin possesses a peculiar 

 odour. The eruption seems to be attended with good consequences, 

 for about twenty-four hours after its appearance both the febrile
