are cut through over the whole body. The red stains are 

 seen on the skins of animals that have died of the disease, 

 long after these skins are dried. They may serve to indicate 

 whether parcels of skins are sound or unsound. There is an 

 infiltration of serum in the subcutaneous areolar tissue, 

 especially of the extremities. 



The mucous membrane of the mouth, lips, soft palate, 

 pharynx, oesophagus, and rumen, is the seat of yellowish or 

 red spots, nodules or vari, and of more or less extensive 

 ulcers. Similar lesions occur over the respiratory organs, and 

 the lungs are often the seat of congestion and ecchymoses. 



The lymphatic glands, especially of the neck, near the 

 anus, and in the mesentery, are enlarged, tumefied, and 

 marked with red spots. 



Prevention and Treatment. From the preceding state- 

 ment it will be gleaned, that prevention of the disease in this 

 country depends on excluding diseased animals from our 

 ports and markets, and on rigid separation of infected animals 

 wherever the disease may appear. The sick animals may be 

 slaughtered ; but if placed where they cannot possibly infect 

 other animals, they may be treated by means of nitre and 

 other neutral salts, and allowing them water and easily 

 digested food. No remedy can be relied upon to cut short 

 the disease, and the utmost that can be done is to diminish 

 the animal's sufferings, and favour a mild course of the disease. 

 Cleanliness, warmth, ventilation, &c., are of the highest im- 

 portance. 



VAEIOLOTTS FEVER IN OTHER ANIMALS. 



Abroad, occasional outbreaks of variola occur amongst 

 goats, pigs, dogs, and domestic fowls, characterised by symp- 

 toms similar to the forms already described.
