development, and unaccompanied by any grave complication. Even 

 in this form the disease appears suddenly, and soon reveals its presence 

 by three clearly marked symptoms — extreme depression, high fever, 

 and deep red or violet tint of the conjunctiva. If you have carefully 

 observed and followed these cases you have noted other morbid pheno- 

 mena. In all the mouth was hot and dr}^, its mucous membrane in- 

 jected, and the gums showed the classical reddish-violet line. The 

 majority showed no intestinal trouble. The faeces were of normal 

 consistence. Three patients were constipated during the earlier 

 period ; only one had diarrhoea. In none was palpation of the abdo- 

 men painful. The circulation was greatly accelerated, the pulse often 

 numbering go per minute, and the force with which the heart beat 

 contrasted markedly with the weakness of the pulse, which was small 

 and thread}^ — in some patients so feeble as to be difficult to count 

 during the first few da3-s. Auscultation of the heart revealed no 

 abnormal sound. The breathing movements were little affected, 

 either in number or rhythm. Auscultation of the lung only showed a 

 trifling exaggeration of the vesicular sound. In one patient, however, 

 during the second and third days the lower portion of both lobes, and 

 especially of the left, was the seat of moist rales and loss of the 

 vesicular murmur^ — signs which were referred to congestion of the 

 lower portion of the lung. This was the only animal which had any 

 attacks of coughing. The skin of the trunk and upper portions of the 

 limbs was hot. In most of the patients the ears and extremities were 

 cold. In almost all the fever was marked, the temperature rising 

 above 40° C. (104° F.), in several even above 41° C. (105*8° F.). 



In two cases the eyes were specially affected. In addition to the 

 epiphora, the violet coloration and infiltration of the conjunctiva, the 

 cornea and deeper portions of the eye showed lesions. In these 

 patients the cornea of both eyes was surrounded by a greyish oede- 

 matous circle, and in one of the two the anterior chamber of the eye 

 contained a deposit resembling hypopyon. These troubles disap- 

 peared in a few days. The fear of light at first observed only per- 

 sisted for forty-eight hours. 



There was no oedematous swelling of the lower parts of the limbs, 

 and no paralysis of the penis or other organs. The rapid diminu- 

 tion in symptoms, prompt and complete resolution, and short con- 

 valescence were particularly remarkable in all cases. The animals 

 were put to work soon after leaving hospital. 



Influenza, however, does not alwa}s present this benign character, 

 and when it takes a malignant form many patients die of intestinal,.
