BOVINE PATHOLOGY. 



latter are those of internal haemorrhage, together with 

 subacute abdominal irritation. Such cases are not amen- 

 able to treatment, but the usual means adopted for 

 internal hasmorrhage must be tried ; administration of 

 haBmostatics, as sulphuric acid, and 

 tannic and gallic acids, &c. Death, 

 however, generally comes on rapidly. 

 The Thyroid Body is large in the 

 ox. It is sometimes the seat of indu- 

 ratioUj but more frequently becomes 

 large, either as a result of colloid 

 change, to which this organ is very 

 liable, or in consequence of the de- 

 velopment of cysts within its sub- 

 stance. Two cases of disease of this 

 body are given in the ' Vetorinarian,' 

 vol. xvi, pp. 194 and 498. It may be 

 removed by operation, if 'so large as to 

 cause inconvenience. Generally its ex- 

 cessive size is only an eyesore, but it 

 may interfere with respiration. 



The Thymus Body of the calf is 

 large, extending far up the neck und 

 into the anterior mediastinum. Some- 

 times it is enlarged. In the 'Vete- 

 rinarian,^ 1852, p. 691, is an account 

 of a case of this nature, in which the 

 organ had undergone tubercular soft- 

 ening, weighed forty- nine ounces, and 

 measured twenty-three inches in its 

 greater circumference. Mr. William 

 Lyon, of Forfar, removed it success- 

 fully by operation. 



We have no record of disease of 

 the Adrenals of the ox.
