INFLUEJJZA. 209 



often staring, and, when so, the attack usually became more 

 severe. This symptom, however, was far from being universal. 

 The extremities were rarely cold. In the course of six or 

 twelve hours, the symptoms became more aggravated, the pulse 

 increased in frequency, and the appetite more diminished, and 

 probably the legs and eyelids considerably swollen. In some 

 cases the respiration became quickened, and in others there was 

 cough and sore throat, but in the majority of my patients there 

 was no bronchial affection wiiatever. 



" In a few instances, the disease quickly reached its acme, but, 

 generally, the symptoms increased in severity for two or three 

 days, when, supposing judicious treatment had been employed, 

 they gradually declined, and at length totally disappeared, the 

 animal slowly regaining his former health and spirits. 



" The bowels, generally speaking, were not apparently much 

 deranged, but their mucous coat was particularly susceptible to 

 the action of aperient medicines; and the fteces were frequently 

 enveloped in thin slimy mucus, and often softer than in a state 

 of health. 



" In some cases the affection of the eyes was so violent as to 

 occasion temporary blindness ; and in others pneumonia was pre- 

 sent, but more frequently severe bronchitis. In many patients 

 the 03dematous swellino- of the le£!;s was enormous, and continued 

 obstinate when the other symptoms had abated ; but, commonly, 

 in proportion as the legs and eyes were much affected, the in- 

 ternal viscera were free from disease, and vice versa. This rule, 

 however, was by no means universal, for in several patients 

 severe cephalic and thoracic symptoms were present in the same 

 subject, and at the same time. 



" When an animal had been previously suffering from some 

 chronic affection, such as diseased or hcpatized lungs, the 

 influenza was almost sure to light up afresh the embers of the 

 former fire, and the local disease generally proved troublesome 

 and obstinate. So, likewise, when from the idiosyncrasy of the 

 animal, an organ was in a weak and susceptible state, inflamma- 

 tion in that part was quickly excited by the general fever pre- 

 sent in the system. 



" The only cases that I have lost were two, with previously 

 diseased lungs. One was an extremely old broken-winded pony 

 that sunk rapidly in the course of two or three days, apparently 

 more from the weakness induced by old age and broken wind 

 than from the amount of new disease, which was by no means 

 great. The other case exhibited, during life, very obscure 

 symptoms, which were subsequently explained in some measure 

 by the most complicated derangements after death. The lungs, 

 the windpipe, the pleura, the pericardium, and the heart itself, 

 as well as tlie liver, exhibited the ravao-es of the most intense
