cause her to spring right into her gait), yet when he simply 
tapped her with the lines she manifested the most willing inclina¬ 
tion to trot as fast as she ever did in her life. 
I examined her and found that there was no doubt that she 
could not hear a sound, though everything about her external 
head was perfectly normal; no tenderness in the region of the 
ears or throat, but she had a discharge from the nostrils when 
her head was held in a dependent position—thus showing that 
there was a collection of pus in the gutteral pouches. Her owner 
was especially anxious to hear my prognosis, and I gave him a 
favorable one, upon the following grounds: The mare had been 
suffering from pharyngitis; the intermittent discharge from the 
nostrils told me that the inflammation had extended up the Eus¬ 
tachian tubes as far as the gutturals, and if it had gone that far 
why could it not extend on up into the middle ear, and by pressure 
of the inflammatory exudation upon the terminal branches of the 
eighth pair of cranial nerves, cause an interference with their 
function ? And as the inflammation should subside, as was most 
likely (the mare being otherwise in perfect health), I argued that 
when the exudation became absorbed there would be a return of 
function. My prognosis has been verified, the animal hearing 
every word spoken to her by her owner when driving her. 
I have never had experience with a case of this nature before, 
and our text books are as mute as a clam upon the subject; and 
since it would be extremely difficult to treat affections of an organ 
situated in the centre of the petrous temporal bone, I think that 
a proper prognosis is of great importance. 
HYSTEROCELE. 
By F. D. Hinebajjoh, V.S., Kalamazoo, Mich. 
Since commencing practice, in the spring of ’87,1 have met with 
two cases of Hysterocele in the mare. The first case occurred 
July 18, ’87, in a Clydesdale mare, the property of L. G. Bragg. 
The mare was first noticed ailing on the 17th. The following day 
the abdomen reached below the hocks. The mare was due to 
fold, and we determined to remove the colt. Upon examination,
