380 INFLUENZA. 



In some cases there seemed abdominal irritation ; the animal 

 crouching, and pawing occasionally with the off fore foot ; 

 bowels sluggish in action, but not constipated. Auscultation 

 showed partial congestion in the lung or lungs, with feeble 

 and peculiar action of the heart." 



The post-mortem appearances of influenza vary according 

 to the character of the disease and the complications which 

 arise during its progress. Very generally there is effusion on 

 the thorax, recent adhesions, evidence of pericarditis, and some- 

 times of inflammation of the pericardium. In all forms of 

 influenza of a rheumatic type, the lesions just named are dis- 

 covered; whereas, in others, there is more evidence of 

 bronchial catarrh, pneumonia, and the blood- changes are 

 indicated by ecchymoses beneath the serous membranes, 

 especially in the cardiac surfaces. 



The treatment of influenza consists in placing the animal 

 where it can breathe fresh air, and be without restraint. A 

 loose box is the best place to keep it in. A mild purge I 

 find usually to benefit the animal, using Cape instead of Bar- 

 badoes aloes. This is followed up by the following: 



Nitrate of potash . . 2 oz. 



Carbonate of ammonia . . 1 oz. 



Solution of the acetate of ammonia . 12 oz. 



Water . . . 12 oz. 



This is to be divided in four doses, to be given night and 

 morning. If effusion in the chest is threatened, I prefer giving 

 digitalis and nitre in diuretic doses thrice daily for a couple 

 of days; and the benefits derived from this treatment are 

 great. Mustard poultices may be applied to the chest, but I 

 do not approve of active blisters, rowels, or setons. When 

 the acute symptoms subside, ferruginous tonics are highly 

 beneficial, and the animals require a liberal diet and mode-
