frequent in the mornigs than in the 

 evenings. The cough is readily brought 

 on by taking cold drinks, odr dusty fo- 

 rrage. by the passing from temperate to 

 cold air. Tuberculose animals that have 

 remained in lying posture for some 

 time, give a short dry cough upon ri- 

 sing. If the cough is very frecuent it 

 becomes sibilant and accompanied by 

 exhaustion and choking. The cough may 

 easilly be brought on, in tuberculous 

 subjects by closing the nasal fossus. 

 The dorsal reflex moreover is usually 

 very marked. 



When the disease is in a very advan- 

 ced stage, the respiratory movements 

 corresponding to inspiration raise the 

 ribs in an exaggerated manner. Very 

 frequently the air expelled is charged 

 whith fetid odours. 



It is difficult to prove the discharge 

 of purulent secretions, altho' such ne- 

 arly always exist, as the diseased sub- 

 jects remove them with their tongue 

 upon licking the nassal fossa?
