served any lesions on the lining membrane of the 

 oesophagus, rumen, reticulum or omasum ; the villous 

 coat of the abomasum is in some cases infiltrated 

 with blood, and ecchymosed. The cavity of the ab- 

 domen occasionally contains an effusion of serum ; the 

 peritoneal tunic is even more rarely inflamed than the 

 other serous membranes, and the intestines are fi'ee 

 from disease, except when the patient sinks from di- 

 arrhoea, in which case they participate in the general 

 morbid changes, and contain fluid and fetid ingesta. 

 The kidnies are sometimes softened, and now and then 

 similar spots to those seen on the lungs exist beneath 

 their capsules ; for the most marked case of which we 

 are indebted to Mr. Ceely, who kindly forwarded the 

 morbid parts for the inspection of Mr. Marson and our- 

 selves. The bladder and other urinary organs are un- 

 affected. The generative system does not participate 

 in the disease, and, according to the French authorities, 

 when an impregnated ewe is carried off by the malady, 

 the foetus gives no indications of it. The spleen is 

 often enlarged, and the liver soft in structure, some- 

 times pale, but more frequently of a dark colour; the 

 condition, however, of this organ in the sheep cannot 

 be said to afford any correct evidence of the existence 

 of small-pox, for it undergoes a variety of structural 

 changes from a multiplicity of causes, some of which 

 are the very reverse of each other. The brain and 

 spinal marrow are affected in some animals, and free 

 from disease in others : simple congestion, either of the 

 meninges, or substance of the encephalon, is the morbid 

 product usually observed. 



It is now our intention to describe the general ma- 

 nagement which should be adopted to mitigate the
