EPIZOOTIC CELLULITIS, OR PINK-EYE. 363 



Swelling of eyelids, often with diffuse redness of the con- 

 junctivte; congestion of the superficial vessels of the eyes, 

 cloudiness of the cornea, and collection of yellowish fibrinous 

 matter or blood -clots in the anterior chambers of the eyes. 

 Sensitiveness to light, eyelids more or less closed, and discharge 

 of tears ; but in milder cases the eye symptoms may not be very 

 distinct. 



Pulse from 50 or GO in mild to 100 or even 120 in severe 

 cases. 



Temperature from 103° or 104° in mild to 106°, 107°, or 

 even 108° in severe cases. 108° was observed in one case only 

 in the College practice, and ended in recovery. During con- 

 valescence the temperature rapidly falls, and in many cases 

 to below the normal — to 99°, and rises to normal — about 101'. 



Gait awkward and slow, loss of tone in the muscles, par- 

 ticularly those of limbs, ears, and lips, and sometimes marked 

 weakness in the hind quarters, and sometimes very great lame- 

 ness. 



The respirations from 15 to 20 in mild to 30 or 40 in grave 

 cases ; these, however, are subject to modifications, as in some 

 horses treated at the College we observed the respiration even 

 slower than natural at first, and increasing in frequency during 

 convalescence. In some fatal cases the breath is foetid for some 

 time before death, and respirations very rapid. 



Mucous membrane of the mouth of a venous red colour ; 

 tongue dry ; fffices at first dry, but on third or fourth day brown 

 and poultice-like in consistence ; later on, diarrhoea in some cases. 



Limbs slightly or considerably swollen ; urine diminished, 

 and sometimes albuminous, and in some cases of a chocolate 

 colour, and containing broken-down blood- corpuscles. 



POST MORTEM APPEAEANCES. 



Heart. — Congested ; sometimes covered with mulberry 

 coloured spots — petechia3. Clots of blood in auricles, ventricles, 

 and larger blood-vessels. 



Blood. — Dark-coloured and viscid; white corpuscles increased 

 in numbers, and many of the red ones broken down. 



Lungs. — Generally congested ; infiltrated with fluid, or filled 

 with blood extravasation, which has undergone decomposition 

 prior to death, and given rise to fcetor of the breath.
