gestion of ono side of tlic brain tlian the otber. The inii)ils may bo 

 dilated or contracted, or we may fiud one condition in one eye and tlie 

 opposite in the other. 



The period of excitement is followed by one of profonnd coma, in 

 which the anijnal is immobile, the head hanging and i)laced against 

 the corner of the stall, the body limp, and the motion, if demanded of 

 the animal, unsteady. Little or no attention will be paid to the sur- 

 rounding noises, the crack of a whip, or even a blow on the surface of 

 the body. The respiration becomes slower, the pulsations are dimin- 

 ished, the coma lasts for variable time, to be followed by excesses of 

 violence, after which the two alternate, but if severe the period of coma 

 becomes longer and longer until the animal dies of spasms of the lungs 

 or of heart failure. It may die from injuries which occur in the ungov- 

 ernable attacks of violence. 



Complication of the feet. — The feet are the organs which are next in 

 frequency predisposed to congestion. This congestion takes place in 

 the laminae (podophyllous structures) of the feet. The stupefied animal 

 is roused from its condition by the excessive pain produced in the feet, 

 and assumes the position of a foundered horse: that is, if the fore feet 

 alone are aflected they are carried forward until they rest on the heels, 

 and if the hind feet are affected all of the feet are carried forward rest- 

 ing on their heels, the hind ones as near the center of gravity as possi- 

 ble. In some cases the stupor of the animal is so great that the pain 

 is not felt, and little or no alternation of the position of th'^ animal is 

 noticeable. The foot is found hot to the touch, and after a given time 

 the depressed convex sole of the typical founder is recognized. Other 

 complications may occur, due to the action of exciting causes, and we 

 may have a severe corysa, laryngitis, pharyngitis or even congestion of 

 the kidneys, followed by nephritis, congestion of the spleen or of any 

 other organ. 



Pleurisy. — This is a rare complication, but when it does occur it is 

 ushered in by the usual symptoms of depression, rapid pulse, small 

 respiration, elevation of the temperature, subcutaneoas cedema of the 

 legs and under surface of the belly, and we find a line of dullness on 

 either side of the chest and an absence of respiratory murmur at the 

 lower part. It is usually severe, and we find an effusion filling one- 

 fourth to one third of the thoracic cavity in from thirty-six to forty-eight 

 hours. 



The laryngo- bronchitis is not a frequent complication nor a very 

 serious one. It is ushered in by a cough, which is rough and fatty, a 

 purulent discharge from the nostrils and an enlargement of the sur- 

 rounding lymphatic ganglia. 



Pericarditis is an occasional compliention of influenza, never occurring 

 alone or in connection with other organs in the chest cavity. It is 

 ushered in by chills, elevation of the temperature; the pulse becomes 

 rapid, thready, and imperceptible. The heart murmurs become indis-
