INFLUENZA. 575 



disease, say on the second or third day, and the pulse is not 

 affected to any great extent, we may regard it as rather a 

 favourable, than an unfavourable, symptom, the swelling 

 being a curative process brought about by an effort of nature, 

 and tending to relieve the fever to a great extent in connec- 

 tion with some other organs. On the other hand, if oedema 

 appears during the latter stages of the disease, in con- 

 nection with a quick or intermittent pulse, it is then a bad 

 sign. 



Influenza frequently terminates in pneumonia, pleurisy, 

 and effusion. When the lungs become affected, the pulse 

 becomes quick and weak, the animal persistently stands, the 

 breathing becomes difficult, appetite completely gone, and in 

 most cases the body and extremities become deathly cold. 

 On auscultation, the characteristic sounds of lung trouble are 

 heard, and on percussion a dull sound is given out. A sub- 

 acute inflammation of the lungs is likelier than any other 

 form to follow influenza. In some cases, when the animal 

 becomes very weak, a lying-down posture may be assumed, 

 and, unless the breathing is too greatly interfered with, 

 it is advisable to let the animal remain in this position. 



Treatment is generally very satisfactory if taken in time. 

 Influenza is a fever, and, like all fevers, runs a certain 

 course, and we must direct our efforts to enable, or help, 

 nature to throw off the disease, and support the animal 

 while the disease is running its course. On no account must 

 we attempt to cut the fever short, as this can be done only 

 at the expense of the patient's life. 



If in a badly ventilated stable or other objectionable place, 

 the animal should be removed at once, and placed in a com- 

 fortable, dry box-stall, well ventilated, but not exposed to 

 draughts. The importanceof plenty of pure air cannot be over- 

 estimated in the treatment of influenza. The animal should 

 be protected from the heat of the sun, if excessive, and in coM
