EPIZOOTIC CELLULITIS, OR PINKEYE, AT CINCINNATI. 329 
It required from five to fifteen days before the disease picked 
upon all the victims that were doomed to become affiicted in any 
one stable. By this behavior of the epizootic the horse owners 
were able to pursue their business without serious interference. 
The violence of the seizures upon the different equines varied 
greatly. Some would appear a little indisposed for a few days, 
while others, especially old ones, would present all the symptoms 
appertaining to the disease in the most virulent form. 
Symptomatology. —Languidness, impaired appetite and pendent 
head are the first appreciable symptoms, usually followed by a 
watery discharge from the eyes, which later, changes to a thick 
mucus. The eyelids puffy, in some cases everted and half closed. 
The cornea appears lusterless and conjunctiva hypersemia. In 
a very small proportion of cases a discharge from the nostrils is 
perceived. The extremities are swollen, tender and hot. The 
swelling may extend clear up to the trunk, involving the sheath 
and vicinity of the linea alba. 
A want of proper co-ordination partly due to an asthenic con¬ 
dition and in part to the inflamed limbs is a constant symptom of 
an aggravated case. Cough is seldom uttered. Impaired deglu¬ 
tition and glandular enlargement about the throat are wanting, 
neither does a redness of the Schneiderian membrane exist. The 
feces may be either tough or soft, mixed with mucous, or in some 
cases diarrhoea is present. The urine during the febrile stage is 
high colored and scanty, but later, the discharge becomes copious, 
with a lighter specific gravity. 
The pulse ranges from 50 to 80 per minute during the first 
three days of sickness. The clinical thermometer may indicate a 
rise in the temperature from 1 to 6 degrees during the first stage, 
but on or after the third day both pulse and temperature drop 
suddenly to almost the normal standard, when the most attention 
is directed to the swollen limbs or affected eyes, as the case may 
be. .Respiration at the outset is invariably increased, but with¬ 
out any abnormal murmurs to be heard on auscultation of the 
lungs if there is no pulmonary disease in connection, which for¬ 
tunately is exceedingly rare. Purpura hemorrhagica has not to 
my knowledge made its appearance as a complication or sequel of
