 but when there is a free discharge from the nasal 

 passage, the cough, though still troublesome, 

 partakes of a moister character. The dulness 

 and lassitude increase, and so does the febrile 

 disturbance. If the temperature is taken it 

 will in all probability be found to be about 

 105 or 106 degrees Fahr., but the temperature 

 of the body with influenza varies. When it 

 is 103 or 104 degrees, the febrile disturbance 

 is comparatively small. Veterinary surgeons 

 usually regard such temperatures as 106 and 

 107 degrees as high ones, and horses do not 

 as a rule continue many days with such rela- 

 tively high temperatures. Thirst is generally 

 very marked, and the animal refuses all food. 

 In the so-called bilious form of this trouble, 

 the liver is implicated, and the visible mucous 

 membranes, also the white portion of the eyes, 

 assume a deep saffron tint. The pulse is gene-

 it is feeble, and the impulse of the heart against 

 the chest wall is, as a rule, during the early 

 stages of the trouble, particularly marked. The 

 rheumatic complications are denoted by swelling
