inclined to the left and held low. The right ear drooped slightly ; 
there was a slight fetor of the breath diagnostic of necrosed tis¬ 
sue. I took all food from her, had her nostrils washed out and 
then watched for the discharge, which I found became clear and 
slightly viscid and was nothing but saliva, which in her efforts to 
swallow had passed back down her nostrils. Examination of the 
fauces showed nothing abnormal, but a relaxed condition of the 
same. Diagnosed a post-pharyngeal abcess, involving the right 
guttural pouch and Eustachian tube. Prognosis very* grave with 
the probability of another post-mortem. The mare’s appetite be¬ 
ing good, I allowed her to eat all she could swallow. Gave elec¬ 
tuaries of potassium chlorate, belladonna and treacle, also enemas 
of alcohol and milk ; applied counter irritant to throat externally. 
After she had got more strength I intended to open the right 
guttural pouch. She was considerably emaciated and quite weak 
from the fact that the greater part of the food she masticated 
passed back through her nostrils, when she tried to swallow, thus 
accounting for the greenish discharge, which was nothing but hay 
mixed with saliva. On the morning of the third day after my 
first visit, I found her condition somewhat changed; her hitherto 
normal temperature was now 104, respiration 25, pulse 76. Di¬ 
agnosed traumatic pneumonia, caused from ingesta passing down 
the trachea in the attempts to swallow. Patient had loss of ap¬ 
petite and great thirst; could swallow but very little, and was in 
considers,ble pain ; she grew rapidly worse and within thirty-six 
hours death came to her relief. I immediately held a post-mor¬ 
tem, and found a gangrenous condition of the right guttural 
pouch; the Eustachian tube of the same side was wholly necrosed 
and the bone surrounding its base was bare. On incising the 
muscles on the corresponding side, I found an abcess containing 
ichorous pus, and a necrotic discharge from the underlying bone. 
The capsular ligament of the occipito-atloid articulation adjacent 
to the abcess was necrosed, and on opening the articulation, I 
found the right condyle of the occipital bone and the correspond¬ 
ing articular cavity of the atlas were badly necrosed. The left 
guttural pouch and adjacent tissues were all normal. On exami¬ 
nation of the trachea, I found inside a quantity of saliva and some
