tion of the mild forms is twelve to fifteen days. Treatment is 

 similar to that of Sheep-pox, and the same precautions should 

 be taken to prevent its dissemination. 



DOG-POX. 



These animals sometimes contract Small-pox or Sheep-pox, 

 and have been supposed to have their own specific form 

 besides. The young suffer most frequently and severely. 

 There is the usual preliminary fever with an eruption on the 

 sides and belly, passing from pimples to vesicles and pustules, 

 and finally drying up into crusts which drop off. The eruption 

 may be discrete or confluent, the latter being very fatal. Similar 

 preventive measures are demanded as in the other forms oi pox. 



BIRD-POX. 



Birds seem susceptible to different forms of variola, having 

 contracted the disease from man in some cases, and in others 

 conveyed it to the sheep. Chickens failed to contract Coiv-pox 

 in the experiments of Roll and myself. It has proved very 

 fatal in chickens, but very slightly so in pigeons, turkeys, 

 and geese. The eruption appears mainly on the head, under 

 the wing, on the tongue, or in the pharynx. In fatal cases 

 death ensued in four or five days. Treatment would rarely 

 be desirable, the great point being to stamp out the malady by 

 destroying the diseased and disinfecting the place. 



APHTHOUS FEVER — FOOT AND MOUTH DISEASE. 



A contagious eruptive fever, attacking cloven-footed animals 

 and communicable to other warm-blooded animals, including 

 even man. Its special feature is the eruption of blisters in the 

 mouth, on the udder and teats, and on the feet. It is only 

 known as communicated by contagion, whether in western 

 Europe, in Great Britain and Ireland, where it was introduced
