perature is not much elevated yet—the thermometer registering 
less than 102° Fahrenheit. 
October 15.—The general appearance of the patients is more 
listless. The febrile symptoms are well established, as indicated 
by the pulse, which numbers from 60 to 90 per minute, and the 
temperature ranging from 102° to 105°. The respiration is very 
much embarrassed. Cough exceedingly painful and hoarse. 
Eyes are mostly closed and cornea have a greyish appearance. 
The discharge from the nostrils varies in different animals; it is 
less frothy ; in some it has changed to a sticky greyish mucus, in 
others to a rusty colored sputa, and in the most aggravated it is 
tinged with blood and coagulated particles of lymph, having the 
appearance of false membrane. The intense redness of lips, 
cheeks and tongue is vanishing. The flow of the salivary secre¬ 
tion is copious. The horses drink but little and even abstain 
from rinsing out their mouths in a pail of water. A few show 
some desire to eat bran-mash and hay. Their coat is staring and 
lusterless. A grey horse called Circus is quite restless ; moves 
to and fro almost continually as far as his halter shank permits 
him. He paws occasionally and looks very anxious. Head ele¬ 
vated, nostrils dilated and respiration very much accelerated. He 
has a pulse of 120 per minute. A roan horse named Sam also 
presents very grave symptoms. He is in a profound state of 
apathy, hardly able to stand on his feet. Pulse almost inpercep- 
tible and respiration stertorous. 
October 16.—Circus and Sam died early this morning. The 
general symptoms of the remaining are intensified. Several 
horses are restless. Bloody discharge from the nostrils prevails 
in some; in others it is thicker and more tenacious. Eyelids are 
either partially or entirely closed. When opened, excoriations of 
cornea the size of a pea are readily observed, surrounded by a 
greyish film. Cough is somewhat looser and less frequent. The 
horses now begin to drink water freely. Their mouths are de¬ 
cidedly better, less swollen and assume a more natural color. 
Circulation as a rule is rapid and weak. In some it is almost im¬ 
perceptible. Heart strokes, however, can be easily felt, varying 
from 54 to 96 per minute. Respiration is very frequent and 
quite noisy owing to the presence of sloughs of the Schneiderian
