DISEASES OF THE OX AND SHEKP. 241 



cud, and then after all the fever may come on again and lead to 

 death. In the month of February, 1884, Mr. J. B. Gresswell 

 found two animals dead out of a herd of forty oxen, and another 

 beast which had a temperature of 106'4°F. died on the next day. 

 Twelve other beasts were affected. In one instance after death 

 the spleen weighed eleven pounds and in another fifteen pounds. 

 On the fifth day another beast succumbed, and the remaining 

 ones recovered under the influence of careful treatment and the 

 wonderful effects of sulphite of sodium, a remedy which is of the 

 greatest possible value. It requires, of course, to be used with 

 care, freshly prepared, recently dissolved in a rather large 

 quantity of pure water, in the correct doses, and for a sufficient 

 period. It is necessary to give small doses well regulated. 



The spleen is quite disintegrated, and if its capsule be cut 

 into, the contents are seen to resemble a mass of black tarry 

 blood in a fluid condition. Especially in cases when the disease

takes a slow course is the spleen implicated, and also in these 

 cases the lungs often become much congested, and decomposition 

 of the extravasated blood occurs, the breath becoming very fetid 

 and death resulting. If the animal has passed large quantities 

 of dark blood during life, the intestines will be found intensely 

 congested and covered with extravasated patches after death. 



On September the 7lh, 1877, the late Mr. D. Gresswell 

 attended a herd of twelve milch cows suckling twelve calves. 

 One was dead on his arrival, its spleen was of very great size, 

 and extravasated patches were seen on the inside lining of the 

 heart. The intestines were inflamed in patches in many places, 

 and abundant extravasations of blood were found on the lining 

 membrane of the paunch, and of the true stomach or abomasum. 



The excrement had been blood-stained during the life of the 

 animal. The lungs in this case were intensely engorged, and 

 were of a very dark purple colour. Three more of the beasts 

 died; but the remaining ones recovered. In spite of all the 

 precautions which were taken, on September the 11th the disease
