Report on Steppe Murrain or Rinderpest. 255 



and neck. The couo:h is more frequent, and a little mucous dis- 

 chargee also comes from the nostrils. The conjunctiva is unin- 

 jected, but the eyes are somewhat intolerant of light. The general 

 surface of the body is chilly, as are the legs, ears, and horns. 



On visiting the animal in the evening, we found that a slight 

 diarrhoea had set in during the day ; that the pulse had risen 

 to 70, and that increasing weakness was existing. There were, 

 however, but few indications that the attack would terminate 

 fatally, the other symptoms remaining about the same. 



May Sth. — The twitchings of the muscles are scarcely to be 

 observed this morning, as is generally the case in the advanced 

 stages of the malady. The diarrhoea is, however, more copious, 

 but yet not alarming ; the pulse is quicker and weaker, and only 

 to be felt at the heart. The breathing has now become some- 

 what increased, but is neither laboured nor difficult. The body 

 is cold, and the animal lies with a drooping head and closed 

 eyes, as in a state of drowsiness, refusing all food, but showing 

 the same disposition to take water. 



The Commissioners explained that they considered there was 

 no chance of the animal's ultimate recovery, although the case 

 would doubtless be a very protracted one. They also said 

 that they had decided to have her killed in the after-part of 

 the day, if we had seen enough of the disease in its mitigated 

 form, that we might institute a. post-mortem examination. This 

 arrangement met with our concurrence, and especially as other 

 cases had occurred since this cow was attacked, and which we 

 were busily engaged in watching the progress of, as by it an 

 opportunity would be afforded of seeing the lesions which were 

 early produced by the malady. 



Sectio Cadaveris. — Respiratory Oryans. — Mucous membrane 

 of the nasal cavities slightly congested, and covered in patches by 

 a small quantity of a yellowish and somewhat viscid discharge. 

 Larynx healthy ; trachea nearly free from injection, but con- 

 taining some thin shreds of colourless lymph lying in close 

 contact with its lining membrane. Bronchia healthy ; lungs 

 perfectly healthy. No effusion into the thorax. 



Circulating Organs. — Heart and its vessels healthy. Blood, 

 dark in colour and but partially coagulated ; the coagulum being 

 very soft. 



Digestive Organs. — Tongue healthy; fauces and velum congested; 

 pharynx and oesophagus, healthy. Rumen healthy, containing 

 a fair amount of ingesta. Reticulum and omasum likewise free 

 from structural disease, and no hardness of the contents of the 

 omasum (loser diirre). Slight efflorescence of the mucous mem- 

 brane of the abomasum in patches was present, while nearly 

 throughout it was likewise dotted over with yellowish points,
