1 70 Diseases of the Respiratory Organs. 



moderates as the pustules cease to form and indicates a 

 tendency to decline. This is the usual or benign 

 condition. Other forms exhibit a tendency to induce 

 bronchitis^ pneumonia or broncho-pneumonia, in which 

 extensive pustular discharges flow from the nostrils, with 

 cough, mucous rale, &c., and in fatal cases stertorous 

 breathing. In the Intestinal form profuse bilious and 

 often offensive evacuations take place. All the forms are 

 attended with extremely fcetid breath and excretions, the 

 skin also emitting the same unpleasant odour. Young 

 dogs are especially liable to contract the disease in whicli 

 mortality is always the greatest, the various stages being 

 developed and merging into each other with remarkable 

 rapidity. 



Treatment of the patient comprises diligent and careful 

 nursing, with mild febrifuges, stimulants and tonics. In 

 warm or mild weather the eruption proceeds most favour- 

 ably, particularly if the animal is sheltered from draughts, 

 but cold winds and exposure generally checks the process 

 of pus -formation, and leads to fatal terminations by 

 implication of important internal organs. Animals re- 

 covering from variola are stated to be free from future 

 attacks of the disease.
